ذِكْرُ الْإِبَاحَةِ لِلْمَرْءِ بَسْطَ ثَوْبِهِ لِلسُّجُودِ عَلَيْهِ عِنْدَ شِدَّةِ الْحَرِّ
we used to pray along with the Messenger of Allah ﷺ in intense heat. When any of us could not rest his face on bare ground while prostrating due to intense heat he spread his cloth and would prostrate on it. (Using translation from Abū Dāʾūd 660)
«كُنَّا إِذَا صَلَّيْنَا مَعَ رَسُولِ اللَّهِ ﷺ فَلَمْ يَسْتَطِعْ أَحَدُنَا أَنْ يُمَكِّنَ جَبْهَتَهُ مِنَ الْأَرْضِ بَسَطَ ثَوْبَهُ فَسَجَدَ عَلَيْهِ»
