Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) relates: the Prophet (peace and blessings be upon him) came to us at our home. I presented a bucket to him; he drank from it and then rinsed his mouth into that bucket.
Al-Bazzar recorded it, and its narrators are thiqat (trustworthy).
