Narrated Ibn Abbas:
When the Prophet got up at night to offer the Tahajjud prayer, he used to say: Allahumma lakal-hamd. Anta qaiyimus-samawati wal-ard wa man fihinna. Walakal-hamd, Laka mulkus-samawati wal-ard wa man fihinna. Walakal-hamd, anta nurus-samawati wal-ard. Walakalhamd, anta-l-haq wa wa’duka-l-haq, wa liqa’uka Haq, wa qualuka Haq, wal-jannatu Han wan-naru Haq wannabiyuna Haq. Wa Muhammadun, sallal-lahu’alaihi wasallam, Haq, was-sa’atu Haq. Allahumma aslamtu Laka wabika amantu, wa ‘Alaika tawakkaltu, wa ilaika anabtu wa bika khasamtu, wa ilaika hakamtu faghfir li ma qaddamtu wama akh-khartu wama as-rartu wama’a lantu, anta-l-muqaddim wa anta-l-mu akh-khir, la ilaha illa anta (or la ilaha ghairuka). (O Allah! All the praises are for you, You are the Holder of the Heavens and the Earth, And whatever is in them. All the praises are for You; You have the possession of the Heavens and the Earth And whatever is in them. All the praises are for You; You are the Light of the Heavens and the Earth And all the praises are for You; You are the King of the Heavens and the Earth; And all the praises are for You; You are the Truth and Your Promise is the truth, And to meet You is true, Your Word is the truth And Paradise is true And Hell is true And all the Prophets (Peace be upon them) are true; And Muhammad is true, And the Day of Resurrection is true. O Allah ! I surrender (my will) to You; I believe in You and depend on You. And repent to You, And with Your help I argue (with my opponents, the non-believers) And I take You as a judge (to judge between us). Please forgive me my previous And future sins; And whatever I concealed or revealed And You are the One who make (some people) forward And (some) backward. There is none to be worshipped but you . Sufyan said that ‘Abdul Karim Abu Umaiya added to the above, ‘Wala haula Wala quwata illa billah’ (There is neither might nor power except with Allah).
Volume 2, Book 21, Number 223:
Allah’s Apostle used to offer eleven Rakat and that was his prayer. He used to prolong the prostration to such an extent that one could recite fifty verses (of the Quran) before he would lift his head. He used to pray two Rakat (Sunna) before the Fajr prayer and then used to lie down on his right side till the call-maker came and informed him about the prayer.
Volume 2, Book 21, Number 227:
Narrated ‘Ali bin Abi Talib
One night Allah’s Apostle came to me and Fatima, the daughter of the Prophet and asked, “Won’t you pray (at night)?” I said, “O Allah’s Apostle! Our souls are in the hands of Allah and if He wants us to get up He will make us get up.” When I said that, he left us without saying anything and I heard that he was hitting his thigh and saying, “But man is more quarrelsome than anything.” (18.54)
