(9) باب صَلاَةِ الْجُمُعَةِ حِينَ تَزُولُ الشَّمْسُ
Iyas b. Salama b. al-Akwa' reported on the authority of his father:
We used to observe the Friday prayer with the Messenger of Allah (ﷺ) when the sun passed the meridian. and we then returned and tried to find out afternoon shadow (of the walls for protecting themselves from the heat of the sun).
