Tirmidhi

´Abu Hurairah narrated that the Messenger of Allah said:` “Our Lord descends every night to the nearest heaven, until the last third of the night remains, so He says: ‘Who is calling upon Me so that I may answer him? Who is asking from Me so that I may give him? And who is seeking forgiveness from Me, so that I may forgive him.’”

´Abu Umamah narrated:` “It was said: ‘O Messenger of Allah, which supplication is most likely to be listened to?’ He said: ‘(During) the last part of the night, and at the end of the obligatory prayers.’”

´Abu Hurairah narrated that a man said:` “O Messenger of Allah, I heard your supplication last night, and the part of it that reached me of it, was that you said: ‘O Allah, forgive me my sin, and expand for me my abode, and bless for me that which You have provided me’ (Allāhummaghfirlī dhanbī, wa wassi` lī fī dārī, wa bārik lī fīmā razaqtanī). He said: ‘Do you see that they leave off anything?’”

´Anas narrated that the Messenger of Allah (ﷺ) said:` “Whoever says in the morning: ‘O Allah we have reached morning, calling You to witness, and calling the carriers of Your Throne to witness, and Your angels, and all of Your creation, that You are Allah, none has the right to be worshipped but You, Alone, without partner, and that Muhammad (ﷺ) is Your slave and Your Messenger. (Allāhumma aṣbaḥnā nush-hiduka wa nush-hidu ḥamalata `arshika wa malā’ikataka wa jamī`a khalqika bi-annaka Allāh, lā ilāha illā anta, waḥdaka lā sharīka laka, wa anna Muḥammadan `abduka wa rasūluk)’ Allah will forgive him for whatever he does that day, and if he says it in the evening, Allah will forgive him for whatever sin he commits that night.”
