Practice Istiḥādah or Qaṣr when expressing grief instead of wailing, shaving head or tearing up clothes.

This hadith is about mourning etiquette according to the Prophet Muhammad (PBUH). When Abu Musa was ill and a woman of his family began to wail, he declared himself free from responsibility for her actions. He said that the Messenger of Allah declared himself free from responsibility for a woman who wails, shaves her head and tears up her clothes. This means that these are not acceptable forms of mourning in Islam. Instead, Muslims should practice Istiḥādah which involves making a small cut on one's clothing or Qaṣr which involves cutting off part of one's clothing as an expression of grief. These acts are more respectful than wailing, shaving one's head or tearing up clothes as they do not involve any extreme behavior or disrespect towards God’s creation.
