It was narrated that Rabi'ah bin Ka'b Al-Aslami said: "I used to stay overnight at the Prophet's ( صلی اللہ علیہ وسلم ) apartment and I used to hear him when he prayed Qiyam at night saying: 'Subhan Allahi Rabil-Alamin (Glory be to Allah, the Lord of the worlds)' for a long time, then he said: 'Subhan Allah wa bi hamdih (Glory and praise be to Allah) for a long time."

It was narrated that Ibn 'Abbas said: "When the Prophet ( صلی اللہ علیہ وسلم ) got up at night to pray Tahajjud, he said: Allahumma, lakal-hamdu anta nurus-samawati wal-ardi wa man fihinna wa lakal-hamdu anta qayyamus-samawati wal ardi wa man fihinna wa lakal-hamdu, anta haqqun wa wa'duka haqqun wal jannatu haqqun wan-nuru haqqun wan-nabiyyuna haqqun wa Muhammadan haqqun, laka aslant wa 'alaika tawakkaltu wa bika amant. (O Allah, to You be praise, You are the Light of the heavens and earth and whoever is in them. To You be praise, You are the Sustainer of the Heavens and the earth and whoever is in them. To You be praise, You are the Sovereign of the heavens and earth and whoever is in them. To You be praise; You are True, Your promise is true, Paradise is true, Hell is true, the Hour is true, the Prophets are true and Muhammad is true. To You have I submitted, in You I put my trust and in You I have believed.'" Then (one of the narrators) Qutaibah mentioned some words the meaning of which was: "Wa bika khasamtu wa ilaika hakamtu, ighfirli ma quadrate wa ma akhkhartu wa ma a'lantu antal-muqaddimu wa antal-mu'khkhir, la ilaha illa anta wa la hawla wa la quwwata illa billah (And with Your help I argue [with my opponents, the non-believers] , and I take You as a judge [to judge between us] . Forgive me my past and future sins and those that I commit openly. You are the One who puts [some people] back and bring [others] forward. There is no God but You and there is no power and no strength except with Allah).'"

It was narrated from Kuraib that 'Abdullah bin 'Abbas told him: He slept at the house of Maimunah the wife of the Prophet ( صلی اللہ علیہ وسلم ), who was his maternal aunt. He said: "I laid down across the mattress an the Messenger of Allah ( صلی اللہ علیہ وسلم ) and his wife lay along it. The Prophet ( صلی اللہ علیہ وسلم ) slept until midnight, or a little before or a little after. The Prophet ( صلی اللہ علیہ وسلم ) woke up and began to rub the sleep from his face with his hand. Then he recited the last ten verses of Surah Al Imran. Then he got up and went to a water skin that was hanging up and performed wudu from it, and he performed wudu well, then he stood up and prayed." Abdullah bin 'Abbas said: "I stood up and did what he had done, then I went and stood beside him. The Messenger of Allah ( صلی اللہ علیہ وسلم ) put his right hand on my neck, and took old of my right hand and tweaked it. Then he prayed two rak'ahs, then two rak'ahs, then two rak'ahs, then two rak'ahs, then two rak'ahs, then two rak'ahs, then he prayed witr.Then he lay down until the Mu'adhdhin came to him and he prayed two brief rak'ahs."

It was narrated from Hudhaifah that: When the Prophet ( صلی اللہ علیہ وسلم ) got up to pray at night, he would brush his teeth with the siwak.

It was narrated that Hudhaifah said: "When the Messenger of Allah ( صلی اللہ علیہ وسلم ) got up to pray tahajjud at night, he would brush his teeth with the siwak.

It was narrated that Hudhaifah said: "We were commanded to use the siwak when we got up to pray at night."

It was narrated that Shaqiq said: "We were commanded, when we got up to pray at night, to clean our mouths with the siwak."

Abu Salamah bin 'Abdur-Rahman said: "I asked 'Aishah: 'With what did the Prophet ( صلی اللہ علیہ وسلم ) start his prayer?' She said: 'When he got up to pray at night he would start his prayer with the words: Allahumma Rabba Jibril wa Maika'il wa Israfil; Fatirus-samawati wal-ard, 'alim al-ghaybi wash-shahadah, anta tahkumu bayna 'ibadika fima kanu fihi yakhtalifun, Allahumma ihdini limakktulifa fihi min al-haqq innaka tahdi man tasha'ila siratin mustaqim (O Allah, Lord of Jibril, Mika'il and Israfil, Creator of the heavens and the earth, Knower of the unseen and the seen, You judge between Your slaves concerning wherein they differ. O Allah, guide me to the disputed matters of truth for You are the One Who guides to the Straight Path)."

It was narrated that Ibn Shihaab said: "Humaid bin Abdur-Rahman bin 'Awf told me that a man from among the companions of the Prophet ( صلی اللہ علیہ وسلم ) said: 'I said, when I was on a journey with the Messenger of Allah ( صلی اللہ علیہ وسلم ): By Allah (SWT), I am going to watch the prayer of the Messenger of Allah ( صلی اللہ علیہ وسلم ) and see what he does. When he prayed 'Isha, he lay down for a long time. Then he woke up and looked toward the horizon and said: "Our Lord! You have not created (all) this without purpose" until he reached: "for You never break (Your) Promise." Then the Messenger of Allah ( صلی اللہ علیہ وسلم ) reached across his bed and took a siwak from it, then he poured water from a vessel and cleaned his teeth. Then he stood and prayed until I said: He has prayed for as long as he has slept. Then he lay down until I said: He has slept as long as he prayed. Then he woke up and did the same as he had done the first time and said the same as he had said. The Messenger of Allah ( صلی اللہ علیہ وسلم ) did that three times before Fajr.'"

It was narrated that Anas said: "Every time we wanted to see the Messenger of Allah ( صلی اللہ علیہ وسلم ) praying at night we saw him, and every time we wanted to see him sleeping, we saw him."
