Asim bin Humayd reported,

I asked Ayesha, "With what did the Messenger of Allah ﷺ begin his night prayer?"She replied, "You have asked me about something no one has asked me about before you. When he stood up, he would say 'Allahu Akbar' ten times, praise Allah ten times, glorify Him ten times, declare His oneness ten times, and seek forgiveness ten times. Then he would say, 'O Allah, forgive me, guide me, and provide for me,' and he would seek refuge from the distress of standing on the Day of Resurrection."

عن عاصم بن حميد قال

سألت عائشة: بأي شيء كان يفتتح رسول الله ﷺ قيام الليل؟ فقالت: لقد سألتني عن شيء ما سألني عنه أحد قبلك، كان إذا قام كبر عشرا، وحمد الله عشرا، وسبح عشرا، وهلل عشرا، واستغفر عشرا، وقال: اللهم اغفر لي، واهدني، وارزقني، ويتعوذ من ضيق المقام يوم القيامة.
