حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، عَنْ مُعَاوِيَةَ بْنِ صَالِحٍ، حَدَّثَنِي أَزْهَرُ بْنُ سَعِيدٍ، عَنْ عَاصِمِ بْنِ حُمَيْدٍ، قَالَ سَأَلْتُ عَائِشَةَ مَاذَا كَانَ النَّبِيُّ ـ صلى الله عليه وسلم ـ يَفْتَتِحُ بِهِ قِيَامَ اللَّيْلِ قَالَتْ لَقَدْ سَأَلْتَنِي عَنْ شَىْءٍ مَا سَأَلَنِي عَنْهُ أَحَدٌ قَبْلَكَ كَانَ يُكَبِّرُ عَشْرًا وَيَحْمَدُ عَشْرًا وَيُسَبِّحُ عَشْرًا وَيَسْتَغْفِرُ عَشْرًا وَيَقُولُ " اللَّهُمَّ اغْفِرْ لِي وَاهْدِنِي وَارْزُقْنِي وَعَافِنِي " . وَيَتَعَوَّذُ مِنْ ضِيقِ الْمُقَامِ يَوْمَ الْقِيَامَةِ .

He usedto say Allahu Akbar ten times, and Al-Hamdu Lillah ten times andSubhan Allah ten times, and he would say Allahumma aghfirli wahdini,warzuqni, wa ‘afini (O Allah, forgive me, guide me, grant meprovisionand give me good health),” and he would seek refuge fromthedifficulty of the standing on the Day of Resurrection.” Translation Not Available
