It was narrated that 'Aishah said:

"I noticed that he was not there one night" and he quoted the rest of the Hadith.

أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا شَرِيكٌ، عَنْ عَاصِمٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ، عَنْ عَائِشَةَ، قَالَتْ فَقَدْتُهُ مِنَ اللَّيْلِ وَسَاقَ الْحَدِيثَ ‏.‏
