Abdullah bin Abbas reported,

Banu Saad bin Bakr sent Dimam bin Thalaba as a delegate to the Messenger of Allah ﷺ. He arrived, made his camel kneel at the door of the masjid, tethered it, and then entered. The Messenger of Allah ﷺ was sitting among his companions. Dimam was a sturdy man, thickly haired, with two long braids. He came forward until he stood before the Messenger of Allah ﷺ among his companions and asked, "Which of you is the son of Abdul-Muttalib?"The Messenger of Allah ﷺ said, "I am the son of Abdul-Muttalib."Dimam asked, "Muhammad?"He replied, "Yes."Dimam said, "Son of Abdul-Muttalib, I am going to question you, and I will be harsh in my questioning, so do not hold it against me."He said, "I will hold nothing against you. Ask whatever you wish."Dimam said, "I adjure you by Allah, your God, the God of those before you, and the God of those who will come after you, has Allah truly sent you to us as a messenger?"He said, "By Allah, yes."Dimam said, "I adjure you by Allah, your God, the God of those before you, and the God of those who will come after you, has Allah truly commanded you to order us to worship Him alone, associating nothing with Him, and to cast off these rivals that our fathers used to worship alongside Him?"He said, "By Allah, yes."Dimam said, "I adjure you by Allah, your God, the God of those before you, and the God of those who will come after you, has Allah truly commanded you that we pray these five prayers?"He said, "By Allah, yes."Then Dimam went on to mention the obligations of Islam one by one, zakat, fasting, Hajj, and all the laws of Islam, adjuring him at each obligation just as he had adjured him at the one before. When he had finished, he said, "I bear witness that there is no god but Allah, and I bear witness that our master Muhammad is the Messenger of Allah. I will carry out these obligations, and I will avoid whatever you have forbidden me. I will add nothing and take nothing away."Then he turned back toward his camel. As he walked away, the Messenger of Allah ﷺ said, "If the man with the two braids is truthful, he will enter Paradise."Dimam reached his camel, untied its tether, and set out until he came to his people. They gathered around him, and the first thing he said was, "How wretched are Lat and Uzza!"They said, "Stop, Dimam! Beware of leprosy and disease, beware of madness!"He said, "Woe to you! By Allah, they can neither harm nor benefit anyone. Allah has sent a messenger and revealed to him a Book by which He has rescued you from what you were in. I bear witness that there is no god but Allah alone, with no partner, and that Muhammad is His servant and messenger. I have come to you from him with what he commands you to do and what he forbids you."By Allah, before that day had ended there was not a man or a woman in his settlement who had not become a Muslim.Ibn Abbas said, "We never heard of any people's delegate better than Dimam bin Thalaba."
