Hadith text
Narrated Abu Dhar Al-Ghifar:We were with the Prophet (ﷺ) on a journey and the Mu'adh-dhin (call maker for the prayer) wanted to pronounce the Adhan (call) for the Zuhr prayer. The Prophet (ﷺ) said, 'Let it become cooler." He again (after a while) wanted to pronounce the Adhan but the Prophet (ﷺ) said to him, "Let it become cooler till we see the shadows of hillocks." The Prophet (ﷺ) added, "The severity of heat is from the raging of the Hell-fire, and in very hot weather pray (Zuhr) when it becomes cooler
Abu Dharr Al-Ghifari bataate hain: "Hum ek safar mein Nabi ke saath the, Muazzin Zuhr ki azaan dena chahta tha. Nabi ne farmaya: 'Thanda hone do.' Usne (kuch der baad) phir chaha, Nabi ne farmaya: 'Thanda hone do yahan tak ke hum pahadon ke saaye dekh lein.'" Nabi ne joda: "Garmi ki shiddat Dozakh ki lapaton se hai, aur sakht garmi mein (Zuhr) thanda hone par padho."
