[Machine] "I heard Abu Umaamah say that the Messenger of Allah ﷺ went on a journey with a group of elderly Ansar who had white beards. He said, 'O people of the Ansar, dye your hair red and wear white garments, and differ from the people of the Book.' We said, 'O Messenger of Allah, the people of the Book wear turbans and do not shave their beards.' The Messenger of Allah ﷺ said, 'Wear turbans and shave your beards, and differ from the people of the Book.' We said, 'O Messenger of Allah, the people of the Book wear sandals and do not wear shoes.' The Prophet ﷺ said, 'Wear sandals and shoes, and differ from the people of the Book.' We said, 'O Messenger of Allah, the people of the Book shorten their clothes and do not wear robes.' The Prophet ﷺ said, 'Shorten your clothes and wear robes, and differ from the people of the Book.'"  

أحمد:٢٢٢٨٣حَدَّثَنَا زَيْدُ بْنُ يَحْيَى حَدَّثَنَا عَبْدُ اللهِ بْنُ الْعَلَاءِ بْنِ زَبْرٍ حَدَّثَنِي الْقَاسِمُ قَالَ

سَمِعْتُ أَبَا أُمَامَةَ يَقُولُ خَرَجَ رَسُولُ اللهِ ﷺ عَلَى مَشْيَخَةٍ مِنَ الْأَنْصَارٍ بِيضٌ لِحَاهُمْ فَقَالَ يَا مَعْشَرَ الْأَنْصَارِ حَمِّرُوا وَصَفِّرُوا وَخَالِفُوا أَهْلَ الْكِتَابِ قَالَ فَقُلْنَا يَا رَسُولَ اللهِ إِنَّ أَهْلَ الْكِتَابِ يَتَسَرْوَلَونَ وَلْا يَأْتَزِرُونَ فَقَالَ رَسُولُ اللهِ ﷺ تَسَرْوَلُوا وَائْتَزِرُوا وَخَالِفُوا أَهْلَ الْكِتَابِ قَالَ فَقُلْنَا يَا رَسُولَ اللهِ إِنَّ أَهْلَ الْكِتَابِ يَتَخَفَّفُونَ وَلَا يَنْتَعِلُونَ قَالَ فَقَالَ النَّبِيُّ ﷺ فَتَخَفَّفُوا وَانْتَعِلُوا وَخَالِفُوا أَهْلَ الْكِتَابِ قَالَ فَقُلْنَا يَا رَسُولَ اللهِ إِنَّ أَهْلَ الْكِتَابِ يَقُصُّونَ عَثَانِينَهُمْ وَيُوَفِّرُونَ سِبَالَهُمْ قَالَ فَقَالَ النَّبِيُّ ﷺ قُصُّوا سِبَالَكُمْ وَوَفِّرُوا عَثَانِينَكُمْ وَخَالِفُوا أَهْلَ الْكِتَابِ
