Sahih Muslim 619b
Khabbab reported: We came to the Messenger of Allah ﷺ and we complained to the Messenger of Allah ﷺ about (saying prayer) on the extremely heated ground (or sand), but he paid no heed to us. Zuhair said: I asked Abu Ishaq whether it was about the noon prayer. He said: Yes. I again said whether it concerned the (offering) of the noon (prayer) in earlier hours. He said: Yes. I said: Did it concern expediting it? He said: Yes.
وَحَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، وَعَوْنُ بْنُ سَلاَّمٍ، - قَالَ عَوْنٌ أَخْبَرَنَا وَقَالَ ابْنُ يُونُسَ، وَاللَّفْظُ، لَهُ حَدَّثَنَا زُهَيْرٌ، - قَالَ حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ سَعِيدِ بْنِ وَهْبٍ، عَنْ خَبَّابٍ، قَالَ أَتَيْنَا رَسُولَ اللَّهِ ﷺ فَشَكَوْنَا إِلَيْهِ حَرَّ الرَّمْضَاءِ فَلَمْ يُشْكِنَا . قَالَ زُهَيْرٌ قُلْتُ لأَبِي إِسْحَاقَ أَفِي الظُّهْرِ قَالَ نَعَمْ . قُلْتُ أَفِي تَعْجِيلِهَا قَالَ نَعَمْ .
