It was narrated from 'Amr bin Shu'aib, from his father, that his grandfather said: “The Messenger of Allah said: 'Whoever is entrusted with an item for safekeeping, is not responsible for it (so long as he is not negligent).' ”
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ الْجَهْمِ الأَنْمَاطِيُّ، حَدَّثَنَا أَيُّوبُ بْنُ سُوَيْدٍ، عَنِ الْمُثَنَّى، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أُودِعَ وَدِيعَةً فَلاَ ضَمَانَ عَلَيْهِ " .
