وَ سُئِلَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنِ الرَّجُلِ يَكُونُ لَهُ عَلَى الرَّجُلِ الدَّرَاهِمُ وَ الْمَالُ فَيَدْعُوهُ إِلَى طَعَامِهِ أَوْ يُهْدِي لَهُ الْهَدِيَّةَ قَالَ لَا بَأْسَ.
Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام was asked about a man who has dirhams or wealth owed to him by another man, and he invites him to his meal or gives him a gift. Imam عليه السلام said: "There is no harm."
