Ishaq ibn Musa al-Ansari narrated to me, Ma'n narrated to us, Malik narrated to us, from 'Abdullah ibn Yazid, the freed slave of al-Aswad ibn Sufyan, from Abu Salama ibn 'Abd al-Rahman and Muhammad ibn 'Abd al-Rahman ibn Thawban, from Abu Hurayra, that the Messenger of Allah, peace and blessings be upon him, said: "When it is hot, delay the prayer until it cools down, for the intensity of heat is from the blast of Hell." And he mentioned: "The Fire complained to its Lord, and He granted it permission for two breaths each year: a breath in winter and a breath in summer."
