Ṣaḥīḥ al-Bukhārī & Ṣaḥīḥ Muslim

Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) sent some cavalry towards Najd. They captured a man from the tribe of Banu Hanīfah called Thumāmah ibn Uthāl, and tied him to one of the pillars of the mosque. Then the Messenger of Allah (may Allah's peace and blessings be upon him) went to him and said: "What do you think, Thumāmah?" He replied, "I have a good thought, O Muhammad!

If you kill, you will kill someone with blood; if you do a favor, you will do a favor to a grateful person; and if you want money, then ask and you will be given whatever you wish." The Messenger of Allah (may Allah's peace and blessings be upon him) left him until the next day, and then said to him: "What do you think, Thumāmah?

He said: "As I told you before: if you do a favor, you will do a favor to a grateful person; if you kill, you will kill a person with blood; and if you want money, then ask and you will be given whatever you wish." The Messenger of Allah (may Allah's peace and blessings be upon him) left him again until the following day and then said to him: "What do you think, Thumāmah?" He said: "I think what I have told you before: if you do a favor , you will do a favor to a grateful person; if you kill, you will kill a person with blood; and if you want money, then ask and you will be given whatever you wish." Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: "Release Thumāmah." Thereupon, he went to a place of water near the mosque, took a bath, and then entered the mosque and said: "I bear witness that there is no god but Allah, and I bear witness that Muhammad is His slave and Messenger.

O Muhammad, by Allah! There was no face on the surface of the earth more hateful to me than yours; but now your face has become the most beloved of all faces to me. By Allah, there was no religion more hateful to me than yours; but now it is the most beloved religion to me. By Allah, there was no city more hateful to me than yours; but now it is the most beloved city to me. Your cavalry arrested me when I was intending to perform ‘Umrah.

And now what do you think?" The Prophet (may Allah's peace and blessings be upon him) gave him glad tidings and ordered him to go and perform ‘Umrah. So, when he went to Mecca, someone said to him: "Have you apostatized?" Thumāmah replied: "No, by Allah! I have embraced Islam along with the Messenger of Allah. Behold, by Allah, no single grain of wheat will come to you from Yamāmah unless the Messenger of Allah gives his permission for it."
