عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ مَا خَطَبَنَا نَبِيُّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِلَّا قَالَ لَا إِيمَانَ لِمَنْ لَا أَمَانَةَ لَهُ وَلَا دِينَ لِمَنْ لَا عَهْدَ لَهُ
It is narrated from Sayyiduna Anas (may Allah be pleased with him), he says: Whenever the Noble Prophet addressed us, he used to say in it: That person has no faith who has no trustworthiness, and that person has no religion who does not keep his promises and covenants.
