[Machine] The Messenger of Allah ﷺ said, "On the day of Friday, there is an hour in which no servant asks for something except that his request is granted." It was asked, "Which hour is it, O Messenger of Allah?" He said, "It is when the sun rises until it reaches its zenith."  

الطبراني:١٤١٣٦ – حَدَّثَنَا عَلِيُّ بْنُ الْمُبَارَكِ ثَنَا إِسْمَاعِيلُ بْنُ أَبِي أُوَيْسٍ حَدَّثَنِي كَثِيرُ بْنُ عَبْدِ اللهِ عَنْ أَبِيهِ عَنْ جَدِّهِ

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «فِي يَوْمِ الْجُمُعَةِ سَاعَةٌ مِنْ نَهَارٍ لَا يَسْأَلُ فِيهَا عَبْدٌ شَيْئًا إِلَّا أُعْطِيَ سُؤْلَهُ» فَقِيلَ أَيَّةُ سَاعَةٍ هِيَ يَا رَسُولَ اللهِ؟ قَالَ «حِينَ تُقَامُ الشَّمْسُ إِلَى انْصِرَافٍ مِنْهَا»
