“I asked ‘Aishah: ‘With what did the Prophet ﷺ start voluntary prayers?’ She said: ‘You have asked me about something which no one has asked before. He used to say Allahu Akbar ten times, and Al-Hamdu Lillah ten times and Subhan Allah ten times, and he would say Allahumma aghfirli wahdini, warzuqni, wa ‘afini (O Allah, forgive me, guide me, grant me provision and give me good health),” and he would seek refuge from the difficulty of the standing on the Day of Resurrection.” (Using translation from Ibn Mājah 1356)  

سَأَلْتُ عَائِشَةَ عَمَّا كَانَ رَسُولُ اللهِ ﷺ يَفْتَتِحُ قِيَامَ اللَّيْلِ؟ قَالَتْ لَقَدْ سَأَلْتَ عَنْ شَيْءٍ مَا سَأَلَنِي عَنْهُ أَحَدٌ كَانَ يُكَبِّرُ عَشْرًا وَيُحَمِّدُ عَشْرًا وَيُسَبِّحُ عَشْرًا وَيَسْتَغْفِرُ عَشْرًا وَيَقُولُ «اللهُمَّ اغْفِرْ لِي وَاهْدِنِي وَارْزُقْنِي وَعَافِنِي» وَيَتَعَوَّذُ مِنْ ضِيقِ الْمُقَامِ يَوْمَ الْقِيَامَةِ
