وَلَا يُسَرَّحُ شَعْرُ الْمَيِّتِ وَلَا لِحْيَتُهُ، وَلَا يُقَصُّ ظُفْرُهُ، وَلَا يُقَصُّ شَعْرُهُ
Translation: The deceased’s hair and beard are not combed; the nails are not clipped, and the hair is not cut.
Yusarrah means to comb or arrange hair; yuqass means to cut. Everyday grooming practices are not automatically included in funeral preparations.
The purpose of washing is purification and dignity, not alteration of the deceased’s hair or nails.
