He narrated a number of ḥadith.

Among those who transmitted from him were al-Miswar ibn Makhramah, Sahl ibn Abī Ḥathmah, Qabīṣah ibn Dhuʾayb, ʿAbd al-Raḥmān al-Aʿraj, ʿUrwah ibn al-Zubayr, Abū Burdah ibn Abī Mūsā, and his own son, Maḥmūd ibn Muḥammad.

He belonged to the Banu al-Ḥāriṭ and was counted among the allies of the Banu ʿAbd al-Ashhal.

He was tall, brown-complexioned, well-proportioned, bald, and dignified in bearing.

ʿUmar appointed him to oversee the zakah of the Juhaynah tribe, and whenever a complaint reached ʿUmar about any governor, he would dispatch Muḥammad to investigate the matter.

He left ten sons and six daughters ﵁.

It is also said that his grandfather’s name was Khālid ibn ʿAdī ibn Majdaʿah.

He advanced to al-Jābiyah and served as the vanguard of ʿUmar’s army.

ʿAbbād ibn Mūsā al-Saʿdī reported: Yūnus related to us—from al-Ḥasan—from Muḥammad ibn Maslamah—who said:

“I passed by and found the Messenger of Allah ﷺ on al-Ṣafā, his hand resting on the hand of a man, so I continued on. He said, ‘What kept you from giving the greeting?’ I replied, ‘O Messenger of Allah, you were doing with this man something I have never seen you do with anyone else, and I disliked interrupting your conversation. Who was he, O Messenger of Allah?’ He said, ‘Gabriel. He told me, “This is Muḥammad ibn Maslamah; he did not greet us. Had he greeted us, we would have returned it to him.”’ I asked, ‘What did he say to you, O Messenger of Allah?’ He replied, ‘He kept advising me about the neighbor until I thought he would command me to make the neighbor an heir.’ (1)"
