Sunnah.com reads: > ‘Abd al-Rahman b. ‘Ajlan reported the Messenger of Allah (May peace be > upon him) as saying : > > Is one of you unable to be like Abu Damdam? The people asked: who is > Abu Damdam? He replied : A man of old before you. He then mentioned > the rest of tradition to the tradition to the same effect. This > version has : who would say (in the morning) : My honors is for the > one who reviles me. Abu Dawud said: This tradition has also been > transmitted by Hashim bin al-Qasim from Muhammad b. 'Adb Allah > al-'Ammi from Thabit on the authority of Anas from Prophet (ﷺ) to the > same effect. Abu Dawud said: The tradition of Hammad (i.e. 'Abd > al-Rahman's version) is sounder. The version in sunnah.com *sounds* somewhat incomplete. Is there a more understandable/complete version in sahih sources?
