وَ رُوِيَ عَنْ وَهْبِ بْنِ وَهْبٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنْ جُعْلِ اَلْآبِقِ وَ اَلضَّالَّةِ قَالَ "لاَ بَأْسَ".
It is narrated from Wahb ibn Wahb, from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام from his father, Imam Muhammad ibn Ali Al-Baqir عليه السلام, who said: I asked Imam عليه السلام about the reward for returning a runaway slave or lost property. Imam عليه السلام said: "There is no harm in it."
