Sunan an-Nasa'i 1617

It was narrated that 'Asim bin Humaid said:"I asked 'Aishah with what did he- meaning the Prophet (ﷺ)- start Qiyam Al-Lail? She said: 'You have asked me something which no one before you has asked. The Messenger of Allah (ﷺ) used to say the takbir ten times, the tahmid ten times, the tasbih ten times, and the tahlil ten times, and pray for forgiveness ten times, and say: Allahummaghfirli, wahdini, warzuqni wa 'afini. A'udhu billahi min diqil-maqami yawmal-qiyamah (O Allah, forgive me, guide me, grant me provision and good health. I seek refuge with Allah from the difficulty of standing on the Day of Resurrection)
