The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَعَنْ عَلِيٍّ قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ تَحْلِقَ الْمَرْأَةُ رَأْسَهَا. رَوَاهُ النَّسَائِيُّ
‘Ali said God's messenger forbade that a woman should shave her head.
Nasa'i transmitted it.
