Struggle for vanity is worthless compared to a struggle for a just cause

A Jubba (i.e. cloak) made of thick silken cloth was presented to the Prophet. The Prophet ﷺ used to forbid people to wear silk. So, the people were pleased to see it. The Prophet ﷺ said, "By Him in Whose Hands Muhammad's soul is, the handkerchiefs of Saʿd bin Muʿadh in Paradise are better than this." Anas added, "The present was sent to the Prophet ﷺ by Ukaidir (a Christian) from Dauma."

أُهْدِيَ لِلنَّبِيِّ ﷺ جُبَّةُ سُنْدُسٍ وَكَانَ يَنْهَى عَنِ الْحَرِيرِ فَعَجِبَ النَّاسُ مِنْهَا فَقَالَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَمَنَادِيلُ سَعْدِ بْنِ مُعَاذٍ فِي الْجَنَّةِ أَحْسَنُ مِنْ هَذَا وَقَالَ سَعِيدٌ عَنْ قَتَادَةَ عَنْ أَنَسٍ إِنَّ أُكَيْدِرَ دُومَةَ أَهْدَى إِلَى النَّبِيِّ ﷺ

[AI] That Uqaydira Duma presented a silk robe to the Messenger of Allah ﷺ and the Messenger of Allah ﷺ wore it. The people admired it, so he said, "Do you admire this? By the One in whose hand is the soul of Muhammad, the handkerchiefs of Sa'd ibn Mu'adh in paradise are better than it." And he gave it to 'Umar, and 'Umar said, "O Messenger of Allah, you dislike it and yet you give it to me?" He said, "O 'Umar, I only sent it to you so that you may use it as a shroud and with it cover a face that will be struck with it, and that is before he forbade silk."

أَنَّ أُكَيْدِرَ دُومَةَ أَهْدَى إِلَى رَسُولِ اللهِ ﷺ جُبَّةَ سُنْدُسٍ فَلَبِسَهَا رَسُولُ اللهِ ﷺ فَعَجِبَ النَّاسُ مِنْهَا فَقَالَ «أَتَعْجَبُونَ مِنْ هَذِهِ؟ فَوَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَمَنَادِيلُ سَعْدِ بْنِ مُعَاذٍ فِي الْجَنَّةِ أَحْسَنُ مِنْهَا» وَأَهْدَاهَا إِلَى عُمَرَ فَقَالَ يَا رَسُولَ اللهِ تَكْرَهُهَا وَأَلْبَسُهَا قَالَ «يَا عُمَرُ إِنِّي إِنَّمَا أَرْسَلْتُ بِهَا إِلَيْكَ لِتَبْعَثَ بِهَا وَجْهًا تُصِيبُ بِهَا وَذَلِكَ قَبْلَ أَنْ يَنْهَى عَنِ الْحَرِيرِ»
