Do not be extravagant in shrouding, for I heard the Messenger of Allah ﷺ say: Do not be extravagant in shrouding, for it will be quickly decayed.  

حَدَّثَنَا عَمْرُو بْنُ هَاشِمٍ أَبُو مَالِكٍ الْجَنْبِيُّ عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ عَنْ عَامِرٍ عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ قَالَ لاَ تَغَالِ لِي فِي كَفَنٍ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ تَغَالَوْا فِي الْكَفَنِ فَإِنَّهُ يُسْلَبُهُ سَلْبًا سَرِيعًا  

Mus'ab b. 'Umari was killed on the day of Uhud. He had only a striped cloak. When we covered his head with it, his feet appeared, and when we covered his feet, his head appeared. Thereupon the Messenger of Allah ﷺ said: Cover his head with it, and cover his feet with some grass.  

رَسُولُ اللَّهِ ﷺ غَطُّوا بِهَا رَأْسَهُ وَاجْعَلُوا عَلَى رِجْلَيْهِ شَيْئًا مِنَ الإِذْخِرِ  

The Prophet ﷺ said: The best shroud is a lower garment and one which covers the whole body, and the best sacrifice is a horned ram.  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ خَيْرُ الْكَفَنِ الْحُلَّةُ وَخَيْرُ الأُضْحِيَةِ الْكَبْشُ الأَقْرَنُ
