وَعَنْ جَابِرِ
قَالَ: كُنْتُ أُصَلِّي الظُّهْرَ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فآخذ قَبْضَة من الْحَصَى لتبرد فِي كفي ن أَضَعُهَا لِجَبْهَتِي أَسْجُدُ عَلَيْهَا لِشِدَّةِ الْحَرِّ
“I used to pray the noon prayer with God’s Messenger, and would take a handful of pebbles to cool them in my palm and lay them down to put my forehead on them when prostrating myself because of the excessive heat.”
