Sahih Al Bukhari (607)

عن عبدالله بن عمر رضي الله عنهما قال "رأى عمر بن الخطاب حلة سيراء عند باب المسجد فقال يا رسول الله لو اشتريتها فلبستها يوم الجمعة وللوفد قال إنما يلبسها من لا خلاق له في الآخرة ثم جاءت حلل فأعطى رسول الله (صلى الله عليه وسلم) عمر منها حلة وقال أكسوتنيها وقلت في حلة عطارد ما قلت فقال إني لم أكسكها لتلبسها فكساها عمر أخا له بمكة مشركا"

`Abdullah ibn `Umar: `Umar ibn Al Khattab (may Allah be pleased with him) saw a silken dress (cloak) being sold at the gate of the Mosque and said: "O Allah's Messenger! Would that you buy it and wear it on Fridays and when the delegates come to you!" Allah's Messenger (peace be upon him) said: "This is worn by the one who will have no share in the Hereafter." Later on some silk dresses were brought and Allah's Messenger (peace be upon him) sent one of them to `Umar. `Umar said: "How do you give me this to wear while you said what you said about the dress of ‘Atarid?" Allah's Messenger (peace be upon him) said: "I have not given it to you to wear." So, `Umar gave it to a pagan brother of his in Makkah.
