Al-Adab Al-Mufrad, Book 2, Hadith 71 (English) ⓘ

Ibn 'Umar said, "'Umar saw a silk robe for sale. He said, 'Messenger of Allah, would you buy this robe and wear it on Jumu'a and when delegations visit you?' He replied, 'Only a person who has no portion in the Next World could wear this.' Then the Messenger of Allah, may Allah bless him and grant him peace, was given some robes made of the same material. He sent one of the robes to 'Umar. 'Umar exclaimed, 'How can I wear it when you said what you said about it?' The Prophet replied, 'I did not give it to you so that you could wear it. You can sell it or give it to someone.' 'Umar sent it to one of his half-brothers by his mother who was still an idolater." (see 26)

حَدَّثَنَا مُحَمَّدُ بْنُ سَلاَمٍ، قَالَ‏:‏ أَخْبَرَنَا عَبْدَةُ، عَنْ عُبَيْدِ اللهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، رَأَى عُمَرُ حُلَّةً سِيَرَاءَ فَقَالَ‏:‏ يَا رَسُولَ اللهِ، لَوِ اشْتَرَيْتَ هَذِهِ، فَلَبِسْتَهَا يَوْمَ الْجُمُعَةِ، وَلِلْوُفُودِ إِذَا أَتَوْكَ، فَقَالَ‏:‏ يَا عُمَرُ، إِنَّمَا يَلْبَسُ هَذِهِ مَنْ لاَ خَلاَقَ لَهُ، ثُمَّ أُهْدِيَ لِلنَّبِيِّ صلى الله عليه وسلم مِنْهَا حُلَلٌ، فَأَهْدَى إِلَى عُمَرَ مِنْهَا حُلَّةً، فَجَاءَ عُمَرُ إِلَى رَسُولِ اللهِ صلى الله عليه وسلم فَقَالَ‏:‏ يَا رَسُولَ اللهِ، بَعَثْتَ إِلَيَّ هَذِهِ، وَقَدْ سَمِعْتُكَ قُلْتَ فِيهَا مَا قُلْتَ، قَالَ‏:‏ إِنِّي لَمْ أُهْدِهَا لَكَ لِتَلْبَسَهَا، إِنَّمَا أَهْدَيْتُهَا إِلَيْكَ لِتَبِيعَهَا أَوْ لِتَكْسُوَهَا، فَأَهْدَاهَا عُمَرُ لأَخٍ لَهُ مِنْ أُمِّهِ مُشْرِكٍ‏.‏
