Umm Salamah asked the Messenger of Allah ﷺ permission for getting herself cupped. He commanded Abu Tibah to cup her. The transmitter said: I think he was her foster-brother or a boy not yet of age. (Using translation from Abū Dāʾūd 4105)
«أَنَّ عَائِشَةَ زَوْجَ رَسُولِ اللَّهِ ﷺ اسْتَأْذَنَتْ رَسُولَ اللَّهِ ﷺ فِي الْحِجَامَةِ فَأَمَرَ النَّبِيُّ ﷺ أَبَا طَيْبَةَ أَنْ يَحْجُمَهَا» قَالَ حَسِبْتُ أَنَّهُ قَالَ «وَكَانَ أَخُوهَا مِنَ الرَّضَاعَةِ أَوْ غُلَامًا لَهُ لَمْ يَحْتَلِمْ»
