sahih

Narrated Hisham's father:

`Aisha used to recommend at-Talbina and used to say, "It is disliked (by the patient) although it is beneficial.''

حَدَّثَنَا فَرْوَةُ بْنُ أَبِي الْمَغْرَاءِ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّهَا كَانَتْ تَأْمُرُ بِالتَّلْبِينَةِ وَتَقُولُ هُوَ الْبَغِيضُ النَّافِعُ‏.‏
