"The Prophet ﷺ was preaching, then Al-Hasan and Al-Husain came, wearing red shirts and stumbling in them. The Prophet ﷺ came down, interrupting himself, and picked them up, then he went back to the minbar and said: 'Allah has spoken the truth: Your wealth and your children are only a trial (At-Taghabun 64:15). I saw these two stumbling in their shirts and I could not continue until I had interrupted myself and picked them up.'" (Using translation from Nasāʾī 1413)  

كَانَ النَّبِيُّ ﷺ يَخْطُبُ فَجَاءَ الْحَسَنُ وَالْحُسَيْنُ عَلَيْهِمَا قَمِيصَانِ أَحْمَرَانِ يَعْثُرَانِ فِيهِمَا فَنَزَلَ النَّبِيُّ ﷺ فَقَطَعَ كَلَامَهُ فَحَمَلَهُمَا ثُمَّ عَادَ إِلَى الْمِنْبَرِ ثُمَّ قَالَ صَدَقَ اللهُ {إنما أَمْوَالُكُمْ وَأَوْلَادُكُمْ فِتْنَةٌ} [التغابن 15] رَأَيْتُ هَذَيْنِ يَعْثُرَانِ فِي قَمِيصَيْهِمَا فَلَمْ أَصْبِرْ حَتَّى قَطَعْتُ كَلَامِي فَحَمَلْتُهُمَا
