659. Commentary:
This narration is weak in its chain of transmission. However, it is established from authentic hadith that leather becomes pure through tanning ("dyeing"), therefore it is permissible to make a prayer mat or clothing from it, and it is not necessary in prostration (sujud) for the forehead to touch the ground or soil directly.
