Sahih Muslim | Book 30 | Hadith Number 5729

Narrated by Anas 'b. Malik
Anas 'b. Malik reported that a person requested Allah's Apostle (may peace be upon him) to give him a very large flock and he gave that to him. He came to his tribe and said: O people, embrace Islam. By Allah, Muhammad donates so much as if he did not fear want. Anas said that the person embraced Islam for the sake of the world but later he became Muslim until Islam became dearer to him than the world and what it contains.
