عَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَشَدَّ تَعْجِيلًا لِلظُّهْرِ مِنْكُمْ وَأَنْتُمْ أَشَدُّ تَعْجِيلًا لِلْعَصْرِ مِنْهُمْ
It is narrated from Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him), he says: We used to perform the Zuhr prayer with the Noble Prophet (peace and blessings be upon him) at the intense heat of midday, but then the Prophet (peace and blessings be upon him) instructed us: Perform this prayer after letting it cool down, for indeed, intense heat is from the steam of Hell.
