It was narrated from Ayyub:

"I heard Hafsah saying: 'Umm 'Atiyyah said: They tied the hair of the daughter of the Prophet in three braids."' 'I said: Did they undo it, then make three braids? She said: 'Yes."'

أَخْبَرَنَا يُوسُفُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا حَجَّاجٌ، عَنِ ابْنِ جُرَيْجٍ، قَالَ أَيُّوبُ سَمِعْتُ حَفْصَةَ، تَقُولُ حَدَّثَتْنَا أُمُّ عَطِيَّةَ، أَنَّهُنَّ جَعَلْنَ رَأْسَ ابْنَةِ النَّبِيِّ ﷺ ثَلاَثَةَ قُرُونٍ . قُلْتُ نَقَضْنَهُ وَجَعَلْنَهُ ثَلاَثَةَ قُرُونٍ قَالَتْ نَعَمْ .
