It was narrated that Anas said:
“The hair of the Messenger of Allah ﷺ was wavy, and (hung down) between his ears and his shoulders.”

يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا جَرِيرُ بْنُ حَازِمٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ كَانَ شَعَرُ رَسُولِ اللَّهِ ـ ﷺ ـ شَعَرًا رَجِلاً بَيْنَ أُذُنَيْهِ وَمَنْكِبَيْهِ.
