(33) باب تَبْرِيدِ الْحَصَى لِلسُّجُودِ عَلَيْهِ
It was narrated that Jabir bin 'Abdullah said:
"We used to pray Zuhr with the Messenger of Allah (ﷺ) and I would take a handful of pebbles in my hand to cool them down, then I would pass them from one hand to the other, and when I prostrated I would put them down to lay my forehead on them."
