Section : Hadith regarding Tahajjud.

The preceding section was primarily concerned with what Allah says about those who perform salatul tahajjud. There also exist a number of ahadith that reinforce the importance of tahajjud.

‘Abdullah ibn as-Salam reports: “When the Prophet sallallahu alehi wasallam came to Medinah, the people gathered around him and I was one of them. I looked at his face and understood that it was not the face of a liar. The first words I heard him say were: ‘O people, spread the salutations, feed the people, keep the ties of kinship, and pray during the night while the others sleep and you will enter paradise in peace.”‘ This is related by al-Hakim, Ibn Majah, and at-Tirmizhi who calls it hasan sahih.

Salman al-Farsi relates that the Prophet sallallahu alehi wasallam said: “Observe the night prayer, it was the practice of the righteous before you and it brings you closer to your Lord and it is penance for evil deeds and erases the sins and repels disease from the body.”

Sahl ibn Sa’d reports: “Gabriel came to the Prophet sallallahu alehi wasallam and said: ‘O Muhammad, live as long as you like, for you are to die. Do whatever deed you wish, for you are to be rewarded. Love whomever you wish, for you are to be parted. And know that the honour of the believer is in the night prayer and his glory is being free from want from the people.”‘

Abu ad-Darda’ reports that the Prophet said: “Three people are loved by Allah, and He laughs for them and He grants them glad tidings. [The first is] a man who fights behind a group that flees and does so with his own soul for Allah’s sake, regardless of whether he is killed or he is aided by Allah and made victorious. Allah says: ‘Look to my slave there who is patient with his life for My sake.’ [The second is] the one who has a beautiful wife and a soft bed and rises during the night. Allah says: ‘He leaves his desires and remembers Me and if he wished he would sleep.’ [The third] is a person who is travelling with a group and they pass the night awake and then sleep, but he still observes his prayer in hardship or ease.”
