The Prophet (SAWA) said, ‘When one of you takes a brother, he must ask him his name, his fathers name, his tribe and his address. This is part of true brotherhood, otherwise it is a foolish amity.
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) : إذا آخى أحَدُكُم رَجُلاً فَلْيَسألْهُ عَنِ اسمِهِ وَاسمِ أبيهِ وقَبيلَتِهِ ومَنزِلِهِ ؛ فَإنّهُ مِن واجِبِ الحَقِّ وصافِي الإخاءِ ، وإلّا فَهِيَ مَوَدَّةٌ حَمْقاءُ.
