حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ ، أَخْبَرَنَا أَيُّوبُ ، عَنْ مُحَمَّدٍ ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : قَالَ أَبُو الْقَاسِمِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " فِي يَوْمِ الْجُمُعَةِ سَاعَةٌ لَا يُوَافِقُهَا مُسْلِمٌ وَهُوَ قَائِمٌ يُصَلِّي يَسْأَلُ اللَّهَ خَيْرًا ، إِلَّا أَعْطَاهُ " ، وَقَالَ بِيَدِهِ ، قُلْنَا : يُقَلِّلُهَا يُزَهِّدُهَا .
Narrated Abu Huraira: Abu-l-Qasim (the Prophet) said, "On Friday there is a particular time. If a Muslim happens to be praying and invoking Allah for something good during that time, Allah will surely fulfill his request." The Prophet pointed out with his hand. We thought that he wanted to illustrate how short that time was.
