The Apostle of Allaah ( sal Allaahu alayhi wa sallam ) used to remember Allaah, the Great and Majestic, at all moments.
Sunan Abi Dawud Book 1, Hadith 18
← Previous Hadith Muhajir came to the Prophet (ﷺ) while he was urinating. He saluted him. The Prophet (ﷺ) did not return the salutation to him until he performed ablution. He then apologised to him, saying: I disliked remembering Allah except in the state of purification.

Sunan Abi Dawud Book 1, Hadith 17 Next Hadith → When the Prophet (ﷺ) entered the privy, he removed his ring.

Abu Dawud said: This is a munkar tradition, i.e. it contradicts the well-known version reported by reliable narrators. On the authority of Anas the well-known version says: The Prophet (ﷺ) had a silver ring made for him. Then he cast it off. The misunderstanding is on the part of Hammam (who is the narrator of the previous tradition mentioned in the text). This is transmitted only by Hammam.
