Riyad as-Salihin, Book 1, Hadith 222 (In-Book)

Abu Musa (May Allah bepleased with him) reported: Messenger of Allah said, "The relationship of the believer with another believer is like (the bricks of) a building, each strengthens the other." He illustrated this by interlacing the fingers of both his hands.[Al-Bukhari and Muslim].

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)‏‏)‏ ‏.‏
