Sunan Ibn Majah 1033
It was
narrated that Anas bin Malik said:
“We used to perform prayer
with
the Prophet (ﷺ) when it was very hot. When one of us could not
place his forehead firmly on the ground, he would spread his garment
and prostrate on it.”
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ بْنِ حَبِيبٍ، حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، عَنْ غَالِبٍ الْقَطَّانِ، عَنْ بَكْرِ بْنِ عَبْدِ اللَّهِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنَّا نُصَلِّي مَعَ النَّبِيِّ ـ صلى الله عليه وسلم ـ فِي شِدَّةِ الْحَرِّ فَإِذَا لَمْ يَقْدِرْ أَحَدُنَا أَنْ يُمَكِّنَ جَبْهَتَهُ بَسَطَ ثَوْبَهُ فَسَجَدَ عَلَيْهِ ‏.‏
