We are now on the threshold of the Month of Allah and the station of the banquet of Allah. I confess that I am not worthy of this banquet. The noble month of Sha'ban, which is the month of the Imams is about to end. We were not able to prepare ourselves for the Month of Allah. Sometimes, I have recited the supplications with and yet they have no effect; in this last part of the month, I am saying, “O Lord! If You did not forgive us during the passed days of Sha`ban, forgive us in its remaining days.” I am not hopeless of the mercy of God, the Exalted, and let it not be so! Let not the day pass in the world when the sins are such that we are hopeless of the mercy of God. My daughter and my dear! In these days it will pass, whether in winning and dinning or in agony and pain, or in negligence of the primordial nature or attention to it.

[Sahifeh-ye Imam, vol. 20, p. 235]

In the holy month of Ramadan, with all the blessings it has, we cannot duly extend gratitude for a single one of these blessings. However, in the holy month of Ramadan if any spiritual stage is attained, one should strive to keep it till the next Ramadan. If that stage is not attained, we should feel regret and strive to attain it. All these tumults are temporary. What will remain is that which is in us. It shall stay and it is with us. We should endeavor to reform our inner self.

[Sahifeh-ye Imam, vol. 20, p. 49]

You must purify yourselves during this Ramadan and every Ramadan. Today, which is probably the last day of Sha`ban, you and I must prepare ourselves for attending “God's Feast”; His banquet, so that, God willing, we enter this great month with spiritual well-being and benefit by the Blessed and Exalted Lord's Light of guidance and so change ourselves for the better. We must really be different in this month as compared to the other months, and must try to comprehend the “Laylat ul-Qadr” (Night of Majesty) and its bounties.

[Sahifeh-ye Imam, vol. 13, p. 32]

The supplications of some of the months and days, especially those that pertain to the month of Rajab, Sha'ban and Ramadan, strengthen the soul miraculously. Of course, I don't say I can understand such realities, but those who are familiar are aware of the effects of the supplications. These supplications open the way for the people. They are the search lights that enable the human being to come out of darkness and into Light] i. e. spiritual vivification. You must pay attention to these supplications.

[Sahifeh-ye Imam, vol. 13, p. 29]

Above all is that one should rectify oneself in the month of Ramadan. We need to purify and refine the self to the last day of our life. Prophets were also in need of this. Grand prophets were also the same, but they had realized their needs and subsequently acted to fulfill their needs. However, since we are veiled, we could not understand our duty and did not fulfill our duties. I hope that this holy month of Ramadan would be a blessing for you. Blessing means that you should plan to act according to the duties God has set for us.

[Sahifeh-ye Imam, vol. 18, p. 396]

This banquet is all about abandonment; abandonment of desires such as for foods, drinks, and other things that human desire requires. God has invited us; that you enter the banquet hall. This banquet is nothing except abandonment; abandonment of carnal desires, abandonment of egotisms, abandonment of selves; abandonment of egoism. All these are in the banquet hall and we have to evaluate and see whether we entered the banquet hall, or we did not enter at all; whether they offered us access to the banquet hall, or not; whether we take benefit from the divine banquet, or not. Of course, the account of the persons like of me, is with kiram al-katibin. But I would like to acquire you, gentlemen, and anyone who would receive these words, particularly the young people: Have you entered to this banquet hall? Did you make use of it? Did you not pay attention to the desires, especially the emotional desires? Or, you just remind like me?

[Sahifeh-ye Imam, vol. 21, pp. 45-6]

Imam stayed in the holy city of Najaf about 14 years and used to tolerate the chilling heat of the region during the summer season. He used to observe fast during the long days. The domestic servant or helper who came to gather dishes after the dawn meal during Ramadan once said to Imam's spouse regarding his food habit as following:
“Honorable lady when I take tray from Imam after dawn meal, I feel nothing of the food stuffs have been consumed. Imam just eats half of a small piece of kutlet (a small piece of cooked traditional Iranian Kebab made from potatoes and minced meat)”.
Imam used to keep fast during these tough long days with the harsh summer conditions.

(A phrase from The Conducts of Imam Khomeini, vol. 3, p. 89)

The holy month of Ramadan had a great significance for Imam to such an extent that he used to cancel most of his meetings in a bid to avail the spiritual virtues during this period. He significantly reduced their daily-based engagements and mostly kept himself busy with reciting Quran and supplications. He used to avoid from reciting or sing verse of poetry in this month and used to initiate a spiritual atmosphere identical to this month.
He used to eat a very less amount of food while consuming his dawn or dinner meals during this honorable month. Sometimes his domestic servant thought he had taken nothing at all.

(A phrase from The Conducts of Imam Khomeini, vol. 3, p. 90)

One of special spiritual schedules of Imam was to regularly saying night prayers during this holy month of Ramadan. One of his closest individual or next to kin describes the memoirs as following:
“I used to silently enter the room where Imam had kept himself busy with prayers in darkness; Imam's devotion towards God the Almighty could easily be felt. He used to kneel down and prostrate in front of God in such a spiritual atmosphere which were really indescribable. I felt that he had really perceived the night of power or decrees during this month which is promised by God to the devotees. Imam had maintained this spiritual state during most or all of his lifetime.”
Imam never gave up his night prayers for about 50 years. He was committed to say his night prayers even during tough circumstances of being in prison, exile or even last days of his life in hospital.

[Persian daily Jamhuri Islami–Islamic Republic–2nd Bahman 1364 AHS, p. 3]

Imam had an indiscernible spiritual state while saying his night prayers. One of his bodyguards says once I had been forced to pass in front of his room during a midnight in the holy month of Ramadan. He came to notice that Imam was shedding his tears and his cries in front of God the Almighty had prevailed over the all surroundings. These all events really influenced me that how Imam had been shedding tears while reciting supplications and sharing the afflictions with God.

[A phrase from The Conducts of Imam Khomeini, vol. 3, p. 126]

The last holy month Ramadan in his lifetime was too much different from the previous ones. Usually Imam kept a handkerchief with him in order to dry his tears while performing worships and supplications. But the handkerchief was not adequate during the last year. He kept towel with him to dry his tears while saying his midnight prayers.
One of his guards says that sometimes he occasionally visited Imam during the last Ramadan of his lifetime and examined a great spiritual transformation and signs of tears on his face. Imam used to dry the stream of tears with a towel.

[A phrase from The Conducts of Imam Khomeini, vol. 3, p. 126]

Imam Khomeini had paid special attention toward Quran as he used to regularly recite verses at least for seven times a day. He never missed any opportunity to maintain contact with the holy book. Imam used each spare moment to recite the Quranic verses even some moments before spreading dining sheets or tables.

[A phrase from The Conducts of Imam Khomeini, vol. 3, p. 8]

One of closest friends of Imam says that once Imam's eyes were suffering from pain and he consulted to a doctor during his stay in the holy city of Najaf. After examining the eyes, the doctor suggested the Imam's eyes need some relief and so he should stop reciting Quran for time being. Imam laughed and said: the doctor, you must do something so I can recite Quran instead of stopping me from doing so. What would be then use of my eyes if I couldn't recite Quran with it.

[Step by Step with the Sun, vol. 1, p. 181]

One of individuals in his closest circle says that Imam used to recite at least ten chapters from the holy Quran. It means he used to finish reciting Quran within three days. This is while other friends were content to finish reciting the holy Quran for twice throughout the month. This is while Imam used to finish at least ten time reciting Quran during the holy month.
