Narrator:Anas ibn Mālik
وَعَن أنسٍ قَالَ: كَانَتْ لِي ذُؤَابَةٌ فَقَالَتْ لِي أُمِّي: لَا أَجُزُّهَا كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَمُدُّهَا وَيَأْخُذُهَا. رَوَاهُ أَبُو دَاوُدَ
Anas said he had a hanging lock of hair and his mother told him not to cut it, for God’s messenger used to stretch it out and hold it. Abu Dawud transmitted it.
