The permissibility of Nabidh so long as it has not become strong and has not become intoxicating Sahih Muslim 2005 b
Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى الْعَنَزِيُّ، حَدَّثَنَا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ، عَنْ يُونُسَ، عَنِ الْحَسَنِ،
عَنْ أُمِّهِ، عَنْ عَائِشَةَ، قَالَتْ كُنَّانَنْبِذُ لِرَسُولِ اللَّهِ صلى الله عليه وسلم فِي سِقَاءٍ يُوكَى أَعْلاَهُ
وَلَهُ عَزْلاَءُ نَنْبِذُهُ غُدْوَةً فَيَشْرَبُهُ عِشَاءً وَنَنْبِذُهُ عِشَاءً فَيَشْرَبُهُ غُدْوَةً .
Translation
'A'isha reported
We prepared Nabidh for Allah's Messenger (ﷺ) in a waterskin, the upper part of which was tied and it (the waterskin) had a hole (in its lower part). We prepared the Nabidh in the morning and he drank it in the evening and we prepared the Nabidh in the night, and he would drink it in the morning.
