It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) sent a detachment towards Najd. The Muslims captured a man named Thumamah bin Uthal, who was the chief of Yamamah, an honorable and wealthy man, and imprisoned him. When he passed by the Noble Prophet (peace and blessings be upon him), the Prophet asked him, "Thumamah, what is your intention?" He replied, "If you kill me, you will be killing a person whose blood is precious. If you show kindness to me, you will be showing kindness to a grateful person. And if you desire wealth, you will get it." Whenever the Noble Prophet (peace and blessings be upon him) passed by him, he would ask him the same question, and he would give the same answer as before. One day, the Noble Prophet (peace and blessings be upon him) said, "Release Thumamah." The people, at his request, took him to a well belonging to the Ansar and gave him a bath. Then he recited the testimony of faith and said, "O Muhammad (peace and blessings be upon him), until yesterday evening, there was no face more disliked by me than yours, no religion more disliked by me than your religion, and no city more disliked by me than your city. But now, your religion is the most beloved of all religions to me, your blessed face is the most beloved of all faces to me, and your city is the most beloved of all cities to me. Your horsemen had captured me while I was going with the intention of performing Umrah. Now, what is your opinion?" The Noble Prophet (peace and blessings be upon him) gave him glad tidings and permitted him to perform Umrah. When he reached Makkah, someone said to him, "Have you also become irreligious?" He replied, "No, rather I have become a Muslim at the hand of Muhammad, the Messenger of Allah (peace and blessings be upon him), and by Allah, after today, not a single grain of food will reach you from Yamamah until the Noble Prophet (peace and blessings be upon him) permits it."
