Quotes & Sayings About Tahajjud

The Prophet once said to his Companions, "Do you want to see a man of Paradise?" A man then passed by, and the Prophet said, "That man is of the people of Paradise." One of Companion of the Prophet wanted to find out what it was about this man that earned him such a commendation from the Messenger of God , so he decided to spend some time with this man and observe him closely. He noticed that this man did not perform the night prayer vigil (tahajjud) or do anything extraordinary. He appeared to be an average man of Medina. The Companion finally told the man what the Prophet had said about him and asked if he did anything special. The man replied, "The only thing that I can think of, other than what everybody else does, is that I make sure that I never sleep with any rancor in my heart towards another." That was his secret. — Hamza Yusuf

Get up to pray in the dark when all are asleep and see how your path is lit and your life begins to shine. — Mufti Ismail Menk

Exercise 1: Guarding the Prayer
Once we are performing the five obligatory prayers with regularity, then it is certainly worth our efforts to begin increasing extra prayers- especially the late-night prayers (tahajjud). Late-night prayer is one of the defining qualities of a salih (righteous) person, also called a wali (friend of Allah). Regarding late-night prayers, Fudayl b. 'Iyyad said that if a man was unable to do them, it was due to his wrong actions during the day. May Allah make us befitting to stand before Him, here and in the hereafter.
