Al-Adab Al-Mufrad, Book 12, Hadith 4 (In-Book) ⓘ

'Abdullah ibn as-Sa'ib reported that his grandfather said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'None of you should take the goods of his companion, either in jest or seriously. When one of you takes his companion's staff, he should return it to him.'"

حَدَّثَنَا عَاصِمُ بْنُ عَلِيٍّ، قَالَ‏:‏ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ عَبْدِ اللهِ بْنِ السَّائِبِ، عَنْ أَبِيهِ، عَنْ جَدِّهِ قَالَ‏:‏ سَمِعْتُ رَسُولَ اللهِ صلى الله عليه وسلم، يَعْنِي، يَقُولُ‏:‏ لاَ يَأْخُذُ أَحَدُكُمْ مَتَاعَ صَاحِبِهِ لاَعِبًا وَلاَ جَادًّا، فَإِذَا أَخَذَ أَحَدُكُمْ عَصَا صَاحِبِهِ فَلْيَرُدَّهَا إِلَيْهِ‏.‏
