عِكْرِمَةُ بْنُ خَالِدٍ، عَنِ ابْنِ عَبَّاسٍ
[Machine] I was at my aunt Maymuna's house. The Prophet ﷺ got up to pray at night, so I stood to his left. He took my hand and placed me on his right. Then he prayed thirteen units of prayer. I observed his standing in each unit just as O' Enveloped One.
كُنْتُ فِي بَيْتِ خَالَتِي مَيْمُونَةَ «فَقَامَ النَّبِيُّ ﷺ يُصَلِّي مِنَ اللَّيْلِ فَقُمْتُ عَنْ يَسَارِهِ فَأَخَذَ بِيَدِي فَجَعَلَنِي عَنْ يَمِينِهِ ثُمَّ صَلَّى ثَلَاثَ عَشْرَةَ رَكْعَةً حَرَزْتُ قِيَامَهُ فِي كُلِّ رَكْعَةٍ قَدْرَ يَا أَيُّهَا الْمُزَّمِّلُ»
