Explanation

Anas ibn Mālik (may Allah be pleased with him) relates: As the Companions were sitting with the Prophet (may Allah's peace and blessings be upon him) in the mosque, a man riding a camel entered, and he made the camel kneel and tied it. Then, he asked them: Who amongst you is Muhammad? Meanwhile, the Prophet (may Allah's peace and blessings be upon him) was reclining among the people. So, we replied: This white man who is reclining. The man said to him: O son of ‘Abdul-Muttalib! The Prophet (may Allah's peace and blessings be upon him) said to him: I have heard you; ask, and I will answer you. The man said to the Prophet (may Allah's peace and blessings be upon him): I will ask you about something and will be hard in questioning. So do not get upset with me. In other words, do not get angry at me or feel annoyed. He replied: Ask whatever you want. He said: I ask you by your Lord and the Lord of those who came before you. Has Allah sent you as a messenger to mankind? He replied: "By Allah, yes," affirming his truthfulness. The man further said: I ask you by Allah. Has Allah ordered you that we must offer the five prayers in a day and night? They are the obligatory prayers. He replied: By Allah, yes. The man further said: I ask you by Allah. Has Allah ordered you to observe fasts during this month of the year? That's the month of Ramadan. He replied: By Allah, yes. The man said: I ask you by Allah. Has Allah ordered you to take this charity from our rich people and distribute it amongst our poor people?" This is Zakah. The Prophet (may Allah's peace and blessings be upon him) replied: By Allah, yes. Thereupon, Dimām embraced Islam and informed the Prophet (may Allah's peace and blessings be upon him) that he would call his people to Islam, and he introduced himself as Dimām ibn Tha‘labah, from Banu Sa‘d ibn Bakr.
