Sunan Ibn Majah 2401
It was narrated from 'Amr  bin Shu'aib, from his father, that his grandfather said:
“The Messenger of Allah (ﷺ) 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 ‏"‏ ‏.‏
