One year, it snowed so much in Qom that half the town was flooded. That year, I witnessed that every night in the Fiziyeh school, Imam, no matter how hard, would break the ice in the fountain and would do his wudhu. Then, in the dark of night, he would say his prayers with sincerity. Till now, I am unable to explain how he was able to be so happy at that time.
This lover of the night would stay awake till the Adhaan of the dawn prayers reciting supplications. At the time of Adhaan, he would go to the Haraam of Hazrat Masuomeh (as) and in the mosque of Balaa Sar, he would say his prayers behind Agha Mirza Jawadi Aqaamalaqi. After prayers he would study. I am able to say that in terms of worship, there were very few like him amongst the religious scholars.
