Is it permissible to uncover one's shoulders while offering Salah (prayer)?
A Muslim is required by Shari`ah to cover his shoulders while praying. To this effect, the Prophet (peace be upon him) is authentically reported to have said:
None of you should offer prayer in a single garment that does not cover the shoulders.
(Recorded by both Al-Bukhari and Muslim.)
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
