The Prophet ﷺ said, "A believer to another believer is like a building whose different parts enforce each other." The Prophet ﷺ then clasped his hands with the fingers interlaced. (At that time) the Prophet ﷺ was sitting and a man came and begged or asked for something. The Prophet ﷺ faced us and said, "Help and recommend him and you will receive the reward for it, and Allah will bring about what He will through His Prophet's tongue."  

عَنِ النَّبِيِّ ﷺ قَالَ الْمُؤْمِنُ لِلْمُؤْمِنِ كَالْبُنْيَانِ يَشُدُّ بَعْضُهُ بَعْضًا ثُمَّ شَبَّكَ بَيْنَ أَصَابِعِهِ وَكَانَ النَّبِيُّ ﷺ جَالِسًا إِذْ جَاءَ رَجُلٌ يَسْأَلُ أَوْ طَالِبُ حَاجَةٍ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ اشْفَعُوا فَلْتُؤْجَرُوا وَلْيَقْضِ اللَّهُ عَلَى لِسَانِ نَبِيِّهِ مَا شَاءَ
