One of Imam Khomeini's disciples quoted:
Imam Khomeini's perseverance was in such manner that despite his old age, nobody could claim to see him wasting his time even for one minute. In the time we were in Imam Khomeini's service, we witnessed that in his life, there is nothing named as free time in people and Islam's affair. For Imam Khomeini, there was no distinction between summer and winter, or a holiday and other days. He always studied or prayed or read the papers came to him.
