صَحِيحُ مُسْلِمٍ
Sahih Muslim 860 b
The Book of Prayer - Friday
Jumu`ah prayer is when the sun has passed its zenith
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا هِشَامُ بْنُ عَبْدِ الْمَلِكِ، حَدَّثَنَا يَعْلَى بْنُ الْحَارِثِ، عَنْ إِيَاسِ بْنِ سَلَمَةَ بْنِ الأَكْوَعِ، عَنْ أَبِيهِ، قَالَ كُنَّا نُصَلِّي مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم الْجُمُعَةَ فَنَرْجِعُ وَمَا نَجِدُ لِلْحِيطَانِ فَيْئًا نَسْتَظِلُّ بِهِ .
Iyas b. Salama b. Akwa' reported on the authority of his father, saying: We used to observe the Friday prayer with the Messenger of Allah (ﷺ), and when we returned we did not find the shadow of the walls in which we could take protection (from the heat of the sun).
