ذِكْرُ قَدْرِ الْمَاءِ الَّذِي كَانَ الْمُصْطَفَى ﷺ وَعَائِشَةُ يَغْتَسِلَانِ مِنْهُ
Hafsa, daughter of 'Abd al-Rahman b. Abu Bakr, reported that 'A'isha narrated to her that she and the Messenger of Allah ﷺ took a bath from the same vessel which contained water equal to three Mudds or thereabout. (Using translation from Muslim 321b)
أَنَّهَا كَانَتْ تَغْتَسِلُ هِيَ وَرَسُولُ اللَّهِ ﷺ مِنْ إِنَاءٍ وَاحِدٍ يَسَعُ ثَلَاثَةَ أَمْدَادٍ أَوْ قَرِيبًا مِنْ ذَلِكَ»
