"Allah’s Messenger (ﷺ) emerged from the toilet, whereupon the meal was presented to him and they said: 'Should we not bring you water for the minor ritual ablution?' He replied: 'I have only been commanded to perform the minor ritual ablution when I get ready for the ritual prayer'.”
"Allah’s Messenger (ﷺ) emerged from having a bowel movement and he was brought a meal, so he was asked: 'Will you not perform the minor ritual ablution?' He replied: “Am I about to perform the ritual prayer, so that I should perform the minor ritual ablution'?”
“I read in the Torah that the blessing of the meal is the minor ritual ablution after it, so I mentioned this to the Prophet (ﷺ), and I informed him of what I had read in the Torah. Allah’s Messenger (ﷺ) then said: ‘The blessing of the meal is the minor ritual ablution before it and the minor ritual ablution after it'!”
