Al-Hajjaj b. Hassan said :

We went in to visit Anas b. Malik, and my sister al-Mughira told me that at that time I was a youth with two plaits of hair (The text mentions <i>qarnan</i> or <i>qussatan</i>. The former would mean two side plaits and the latter two plaits over the forehead. The alternative is given evidently because the transmitter is not sure which was the correct word), and he wiped my head, invoked a blessing on me and said, “Shave these two, or clip them, for this is the style of the Jews.” Abu Dawud transmitted it.

وَعَن الحجاح بْنِ حَسَّانَ قَالَ دَخَلْنَا عَلَى أَنَسِ بْنِ مَالك فَحَدَّثَتْنِي أُخْتِي الْمُغِيرَةُ قَالَتْ: وَأَنْتَ يَوْمَئِذٍ غُلَامٌ وَلَكَ قَرْنَانِ أَوْ قُصَّتَانِ فَمَسَحَ رَأْسَكَ وَبَرَّكَ عَلَيْكَ وَقَالَ: «احْلِقُوا هَذَيْنِ أَوْ قُصُّوهُمَا فَإِنَّ هَذَا زِيُّ الْيَهُود» . رَوَاهُ أَبُو دَاوُد
