Sayyiduna Mahmud bin Rabi’ radiyallahu ‘anhu narrates that I remember the Messenger of Allah sallallahu ‘alayhi wa sallam very well, and I also remember him rinsing his mouth from the bucket at my house (which he poured into my mouth). Then he narrated the previous hadith from Sayyiduna ‘Itban bin Malik al-Ansari radiyallahu ‘anhu.
