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.  

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  

Yahya related to me from Malik from Yazid ibn Abdullah ibn al-Had from Muhammad ibn Ibrahim ibn al-Harith at-Taymi from Abu Salama ibn Abd ar-Rahman ibn Awf that Abu Hurayra said, "I went out to at-Tur (Mount Sinai) and met Kab al Ahbar and sat with him. He related to me things from the Tawrah and I related to him things from the Messenger of Allah ﷺ. Among the things I related to him was that the Messenger of Allah ﷺ said, 'The best of days on which the sun rises is the day of jumua. In it Adam was created, and in it he fell from the Garden. In it he was forgiven, and in it he died. In it the Hour occurs, and every moving thing listens from morning till sunset in apprehension of the Hour except jinn and men. In it is a time when Allah gives toa muslim slave standing in prayer whatever he asks for.' Kab said, 'That is one day in every year.' I said, 'No, in every jumua.' Then Kab recited the Tawrah and said, 'The Messenger of Allah has spoken the truth.' "

Abu Hurayra continued, "I met Basra ibn Abi Basra al-Ghiffari and he said, 'Where have you come from?' I said, 'From at-Tur.' He said, 'If I had seen you before you left, you would not have gone. I heard the Messenger of Allah ﷺ say, "Only make a special journey to three mosques: the mosque of the Haram (Makka), this mosque (Madina), and the mosque of Ilya or the Bait al-Maqdis (two names of Jerusalem)." ' " (He was not sure which expression was used.)

Abu Hurayra continued, "Then I met Abdullah ibn Salam and I told him that I had sat with Kabal-Ahbar, and I mentioned what I had related to him about the day of jumua, and told him that Kab had said, 'That is one day in every year.' Abdullah ibn Salam said, 'Kab lied,' and I added, 'Kab then recited the Tawrah and said, "No, it is in every jumua.'' ' Abdullah ibn Salam said, 'Kab spoke the truth. 'Then Abdullah ibn Salam said, 'I know what time that is.' "

Abu Hurayra continued, "I said to him, 'Let me know it - don't keep it from me.' Abdullah ibn Salam said, 'It is the last period of time in the dayof jumua.' "

Abu Hurayra continued, "I said, 'How can it be the last period of time in the day of jumua, when the Messenger of Allah ﷺ said, "a muslim slave standing in prayer", and that is a time when there is no prayer?' Abdullah ibn Salam replied, 'Didn't the Messenger of Allah ﷺ say, "Whoever sits waiting for the prayer is in prayer until he prays?" "'

Abu Hurayra added, "I said, 'Of course.' He said, 'Then it is that.' "
