وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ ح وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكِ بْنِ أَنَسٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم ذَكَرَ يَوْمَ الْجُمُعَةِ فَقَالَ ‏"‏ فِيهِ سَاعَةٌ لاَ يُوَافِقُهَا عَبْدٌ مُسْلِمٌ وَهُوَ يُصَلِّي يَسْأَلُ اللَّهَ شَيْئًا إِلاَّ أَعْطَاهُ إِيَّاهُ ‏"‏ ‏.‏ زَادَ قُتَيْبَةُ فِي رِوَايَتِهِ وَأَشَارَ بِيَدِهِ يُقَلِّلُهَا.
