وَعَن عطاءِ بن يسارٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْمَسْجِدِ فَدَخَلَ رَجُلٌ ثَائِرُ الرَّأْسِ وَاللِّحْيَةِ فَأَشَارَ إِلَيْهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِيَدِهِ كَأَنَّهُ يَأْمُرُهُ بِإِصْلَاحِ شَعْرِهِ وَلِحْيَتِهِ فَفَعَلَ ثُمَّ رَجَعَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَلَيْسَ هَذَا خَيْرًا مِنْ أَنْ يَأْتِيَ أَحَدُكُمْ وَهُوَ ثَائِرُ الرَّأْسِ كَأَنَّهُ شَيْطَان» . رَوَاهُ مَالك
Ata ibn Yasar reported: The Messenger of Allah ﷺ was in the mosque when a man came in with disheveled hair and beard. The Messenger of Allah ﷺ gestured to him with his hand as if telling him to groom his hair and beard. The man did so, then returned. The Messenger of Allah ﷺ said, “Is this not better than one of you coming in with disheveled hair, looking like a devil?” Malik transmitted it.
