Imām Bukhārī narrates: 'Umar ibn Hafs narrated to us, he said: My father narrated to us, he said: Al-A'mash narrated to us, he said: Abū Sālih narrated to us, from Abū Sa'īd, may Allāh be pleased with him, he said: The Messenger of Allāh ﷺ said:

Pray Zuhr in the cooler time, because the intensity of heat is from the raging of the Fire.

Sufyān, Yahyā, and Abū 'Awānah have corroborated Hafs ibn Ghiyāth in narrating from al-A'mash.
