I would like to know if the Hadith about Abu Dam Dam (radiyallahu ‘anhu) is sound and if you could please provide the Arabic.
You are probably referring to the following Hadith:
Rasulullah (sallallahu ‘alayhi wa sallam) once said, ‘Why can’t you be like Abu Dam Dam?’ The Sahabah asked, ‘Who is Abu Dam Dam O Rasulullah?’He replied, ‘Abu Dam Dam recites the following du’a every morning, ‘Allahumma inni qad wahabtu nafsi wa ‘irdi laka.‘ He would not retaliate or swear at those who swore him, oppressed him or abused him.
(‘Amalul Yawmi Wal Laylah of Ibnus Sunni, Hadith: 66. Also see Al Adhkar, Hadith: 235)
Imam Abu Dawud (rahimahullah) has recorded this narration with variation in the wording.
(Sunan Abi Dawud, Hadith: 4886-4887)
The narration is corroborated and suitable to quote.
(Refer: Nataijul Afkar, vol. 2 pg. 415-419)
Arabic text of the du’a in Ibnus Sunni:
اللهم إنِّي قَدْ وَهَبْتُ نَفْسِي وَعِرْضِي لَك
O Allah! I offer my life and honour to you [I have given my life and honour in charity to those who oppress me]
And Allah Ta’ala Knows best.
