وعن أبي موسى رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم " المؤمن للمؤمن كالبنيان يشد بعضه بعضًا" وشبك بين أصابعه . ((متفق عليه)) .
Messenger of Allah (ﷺ) said, "The relationship of the believer with another believer is like (the bricks of) a building, each strengthens the other." He (ﷺ) illustrated this by interlacing the fingers of both his hands.[Al-Bukhari and Muslim].
