While we were sitting with the Prophet (ﷺ) in the mosque, a man came riding on a camel. He made his camel kneel down in the mosque, tied its foreleg and then said: " Who amongst you is Muḥammad?" At that time the Prophet (ﷺ) was sitting amongst us (his companions) leaning on his arm. We replied, "This white man reclining on his arm." The man then addressed him, "O son of ' Abdul Muttalib." The Prophet (ﷺ) said, "I am here to answer your questions ". The man said to the Prophet (ﷺ) " I want to ask you something and will be hard in questioning. So do not get angry." The Prophet (ﷺ) said, Ask whatever you want." The man said, I ask you by your Lord, and the Lord of those who were before you, has Allâh sent you as a Messenger (ﷺ) to all the mankind?" The Prophet (ﷺ) replied, "By Allâh, yes." The man further said, "I ask you by Allâh. Has Allah ordered you to offer five (prayers) in a day and night (24 hours).? He replied, "By Allâh, yes. The man further said, "I ask you by Allah ! Has Allâh ordered you to observe Şaum (fasts) during this month of the year (i.e. Ramaḍân)?" He replied, "By Allâh, yes." The man further said, "I ask you by Allâh. Has Allah ordered you to take Zakât from our rich people and distribute it amongst our poor people? The Prophet (ﷺ) replied, "By Allâh, yes ". Thereupon that man said, "I believe in all that with which you have been sent, and I have been sent by my people as a Messenger (ﷺ), and I am Dimâm bin Tha‘laba from the brothers of Bani Sa'd bin Bakr."
