Reserving Pre Dawn for Namaz e Shab

During the day Ibrahim Hadi (rh) was a very humorous man, and he talked very simply. But at nights, he usually woke up before praying time and prayed the Night Prayer (Tahajjud- which is not obligatory). He tried to do this secretly. As Ibrahim got closer to the end of his life, his awakening before dawn became longer. It was as if he knew that it has been said in the traditions that the sign of being a Shi’a Muslim was to awaken before dawn and pray the Night Prayer.
