Q 2: Is it permissible
to offer Salah (Prayer) in sleeping garments or sports wear?
Muslims should take their adornment by wearing clean clothes when they go to Salah, in submission to the Saying of Allah (Exalted be He):
O Children of Adam! Take your adornment (by wearing your clean clothes), while praying [and going round (the Tawâf of) the Ka‘bah,]
This means whenever you go to offer Salah. However, if the sleeping garments or (Part No. 5; Page No. 142) the sports clothing cover a person's `Awrah (parts of the body that must be covered in public) and they are pure, the person's Salah in these clothes is valid.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
