عَنْ أَبِي مُوسَى رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((الْمُؤْمِنُ لِلْمُؤْمِنِ كَالْبُنْيَانِ يَشُدُّ بَعْضُهُ بَعْضًا))
Sayyiduna Abu Musa (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: A believer to another believer is like a building, parts of which strengthen one another.
