(19) باب صَلاَةُ الأَوَّابِينَ حِينَ تَرْمَضُ الْفِصَالُ
Zaid b. Arqam, on seeing some people praying in the forenoon, said:
They well know that prayer at another time than this is more excellent, for Allah's Messenger (ﷺ) said: The prayer of those who are penitent is observed when your weaned camels feel the heat of the sun. (ID)
