Muwatta Imam Malik Book of Jumu'a, Hadith 16

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ mentioned the day of jumua and said, "There is a time in it when Allah gives to a muslim slave standing in prayer whatever he asks for," and the Messenger of Allah ﷺ indicated with his hand how small it was.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ ذَكَرَ يَوْمَ الْجُمُعَةِ فَقَالَ " فِيهِ سَاعَةٌ لاَ يُوَافِقُهَا عَبْدٌ مُسْلِمٌ وَهُوَ قَائِمٌ يُصَلِّي يَسْأَلُ اللَّهَ شَيْئًا إِلاَّ أَعْطَاهُ إِيَّاهُ " . وَأَشَارَ رَسُولُ اللَّهِ ﷺ بِيَدِهِ يُقَلِّلُهَا .
