Imam would stay awake until dawn during Ramadan

Haj Ahmed Agha narrates:  One night during the month of Ramadhan, I was sleeping on the rooftop.  Imam's house was small being only 45 square meters.  I woke up and heard a sound.  I realized that Imam was saying his prayers in the dark.  His hands were stretched out towards the sky and he was crying.
 
During Ramadhan, it was Imam's routine that he would stay awake until dawn reciting prayers and supplications.  After the dawn prayers he would rest a little and then get ready for his work.
