Hadith 15:507
A hadith like this has been narrated on the authority of Mansur, but he did not mention:
" On that very day He created the heavens and the earth," and he (the narrator) substituted the word" fighting" (qital) for" killing" (qatl), and further said:" No one is to pick up the dropped thing except one who makes a public announcement of it."
وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ، حَدَّثَنَا مُفَضَّلٌ، عَنْ مَنْصُورٍ، فِي هَذَا الإِسْنَادِ بِمِثْلِهِ وَلَمْ يَذْكُرْ " يَوْمَ خَلَقَ السَّمَوَاتِ وَالأَرْضَ " . وَقَالَ بَدَلَ الْقِتَالِ " الْقَتْلَ " . وَقَالَ " لاَ يَلْتَقِطُ لُقَطَتَهُ إِلاَّ مَنْ عَرَّفَهَا "
