´It was narrated that Abu Sa'eed Al-Khudri said:` "The Messenger of Allah [SAW] forbade Ishtimal As-Samma' and wrapping oneself in a single garment (that did not cover the private parts)."
Explanation & Benefits
Hafiz Muhammad Ameen
(1) “Ishtimal as-Samma’” in the language refers to wrapping oneself in such a way that the hands and so on become enclosed and, if needed, cannot be easily taken out. In Punjabi, this is called “kehnday bukal.” May Allah protect us, if a person is about to fall, he would not be able to save himself with his hands. If someone attacks and runs away, he would not be able to catch him. However, the jurists (fuqaha) have explained its meaning as wrapping the body with a single garment, with no other garment, and then lifting it from one side and placing it over the shoulder, leaving the other side exposed so that the obligatory covering (‘awrah) is not maintained. This situation is, by consensus, forbidden (haram) because being naked is not permissible. The first situation is also not appropriate. Although there is no legal (shar‘i) harm in it, it is not correct in prayer (salah) because one would have to keep adjusting the wrap repeatedly and the garment would keep slipping. Instead of focusing on the prayer, attention would be diverted to fixing the garment.
(2) “Goth marna” is to tie the upper sheet (chadar) around the waist and both knees while the knees are upright and the anus and feet are on the ground. In this too, there is the same problem as with the wrap (bukal), that a person becomes somewhat restricted. If he needs to get up quickly, it becomes difficult. Also, in the case of a sheet or similar garment, there is a risk of the private parts (‘awrah) being exposed.
