Abdullah bin Umar reported,

Umar bin Khattab saw a silk garment for sale at the door of the mosque and said, "Messenger of Allah, if only you would buy this and wear it on Fridays and when delegations come to visit you."The Messenger of Allah ﷺ replied, "Only those who have no share in the Hereafter wear this."Later, garments of this kind were brought to the Messenger of Allah ﷺ, and he gave one of them to Umar bin Khattab رضي الله عنه.Umar said, "Messenger of Allah, you have given me one to wear, yet you said what you said about the garment of Utarid?"The Messenger of Allah ﷺ answered, "I did not give it to you so that you would wear it yourself."So Umar bin Khattab رضي الله عنه gave it to a polytheist brother of his in Mecca.

حدثنا عبد الله بن يوسف قال أخبرنا مالك عن نافع

عن عبد الله بن عمر

أن عمر بن الخطاب رأى حلة سيراء عند باب المسجد فقال يا رسول الله لو اشتريت هذه فلبستها يوم الجمعة وللوفد إذا قدموا عليك فقال رسول الله ﷺ إنما يلبس هذه من لا خلاق له في الآخرة ثم جاءت رسول الله ﷺ منها حلل فأعطى عمر بن الخطاب رضي الله عنه منها حلة فقال عمر يا رسول الله كسوتنيها وقد قلت في حلة عطارد ما قلت قال رسول الله ﷺ إني لم أكسكها لتلبسها فكساها عمر بن الخطاب رضي الله عنه أخا له بمكة مشركا
