Narrated Um Salama:

The Prophet came to me while there was an effeminate man sitting with me, and I heard him (i.e. the effeminate man) saying to 'Abdullah bin Abi Umaiya, "O 'Abdullah! See if Allah should make you conquer Ta'if tomorrow, then take the daughter of Ghailan (in marriage) as (she is so beautiful and fat that) she shows four folds of flesh when facing you, and eight when she turns her back." The Prophet then said, "These (effeminate men) should never enter upon you (O women!)." Ibn Juraij said, "That effeminate man was called Hit."

حَدَّثَنَا الْحُمَيْدِيُّ، سَمِعَ سُفْيَانَ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ ابْنَةِ أَبِي سَلَمَةَ، عَنْ أُمِّهَا أُمِّ سَلَمَةَ ـ رضى الله عنها ـ دَخَلَ عَلَىَّ النَّبِيُّ ﷺ وَعِنْدِي مُخَنَّثٌ فَسَمِعْتُهُ يَقُولُ لِعَبْدِ اللَّهِ بْنِ أَبِي أُمَيَّةَ يَا عَبْدَ اللَّهِ أَرَأَيْتَ إِنْ فَتَحَ اللَّهُ عَلَيْكُمُ الطَّائِفَ غَدًا فَعَلَيْكَ بِابْنَةِ غَيْلاَنَ، فَإِنَّهَا تُقْبِلُ بِأَرْبَعٍ وَتُدْبِرُ بِثَمَانٍ. وَقَالَ النَّبِيُّ ﷺ
" لاَ يَدْخُلَنَّ هَؤُلاَءِ عَلَيْكُنَّ ". قَالَ ابْنُ عُيَيْنَةَ وَقَالَ ابْنُ جُرَيْجٍ الْمُخَنَّثُ هِيتٌ. حَدَّثَنَا مَحْمُودٌ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ هِشَامٍ بِهَذَا، وَزَادَ وَهْوَ مُحَاصِرٌ الطَّائِفَ يَوْمَئِذٍ.
