It was narrated from Ibn Buraidah that:

His father said: "While the Messenger of Allah ﷺ was on the minbar, Al-Hasan and Al-Husain came,wearing red shirts, walking and stumbling. He came down and picked them up, then said: 'Allah has spoken the truth: Your wealth and your children are only a trial.' I saw these two walking and stumbling in their shirts, and I could not be patient until I went down and picked them up.'"

أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا أَبُو تُمَيْلَةَ، عَنِ الْحُسَيْنِ بْنِ وَاقِدٍ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ بَيْنَا رَسُولُ اللَّهِ ﷺ عَلَى الْمِنْبَرِ يَخْطُبُ إِذْ أَقْبَلَ الْحَسَنُ وَالْحُسَيْنُ عَلَيْهِمَا السَّلاَمُ عَلَيْهِمَا قَمِيصَانِ أَحْمَرَانِ يَمْشِيَانِ وَيَعْثُرَانِ فَنَزَلَ وَحَمَلَهُمَا فَقَالَ " صَدَقَ اللَّهُ { إِنَّمَا أَمْوَالُكُمْ وَأَوْلاَدُكُمْ فِتْنَةٌ } رَأَيْتُ هَذَيْنِ يَمْشِيَانِ وَيَعْثُرَانِ فِي قَمِيصَيْهِمَا فَلَمْ أَصْبِرْ حَتَّى نَزَلْتُ فَحَمَلْتُهُمَا " .
