Sayyiduna Abu Dharr (may Allah be pleased with him) narrates that the Prophet’s (peace and blessings be upon him) muezzin (Sayyiduna Bilal, may Allah be pleased with him) gave the call to prayer for Zuhr, so the Prophet (peace and blessings be upon him) said:“Cool it, cool it,”or he said:“Wait, wait,”and he said:“The intensity of the heat is from the boiling of the fire of Hell, so when the heat becomes severe, perform the prayer at a cooler time.”(Then the call to prayer for Zuhr was given at a time) when we could see the shadows of the mounds.
