Reports on tearing the shroud

Al-Hasan and Muhammad (Ibn Sirin) used to dislike that the shroud of the deceased be torn when he is placed in the grave.

Abdullah bin Qays bin Ubad narrates from his father that he left instructions: "When you place me in my grave, tear the part of the shroud that is next to my body, so that you entrust me to the earth in the true sense."
