Zaid bin Wahb narrates: He heard Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) saying: We were traveling with the Prophet Muhammad (peace and blessings be upon him). The muezzin intended to give the call to prayer for the Zuhr prayer, so the Prophet (peace and blessings be upon him) said to him: Let it cool down. Then he intended to give the call to prayer, so the Prophet (peace and blessings be upon him) said to him: Let it cool down. This happened two or perhaps three times, until we saw the shadows of the hills. Then the Prophet (peace and blessings be upon him) said: The severity of the heat is part of the heat of Hell, so when the heat is intense, perform (the Zuhr) prayer at a cooler time. (Imam Ibn Hibban, may Allah have mercy on him, says:) Abu al-Hasan Ubaid bin Hasan is a Muhajir from Kufa.
