- وَبِهَذَا الْإِسْنَادِ، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: «فِي الْجُمْعَةِ سَاعَةٌ لَا يُوَافِقُهَا مُسْلِمٌ يُصَلِّي يَسْأَلُ اللَّهَ فِيهَا خَيْرًا إِلَّا آتَاهُ اللَّهُ إِيَّاهُ مَا لَمْ يَسْأَلْ مَأْثَمًا أَوْ قَطِيعَةَ رَحِمٍ»
مسند إسحاق بن راهويه (1/ 370)
The Messenger of Allah (ﷺ) said while talking about the merits of Friday, "There is a time on Friday at which a Muslim, while he (or she) is performing Salat and is supplicating, will be granted whatever he (or she) is supplicating for as long as he does not ask for sin or breaking of family ties.
