Sahih Bukhari Volume 9, Book 93, Hadith Number 626.

Narrated By Al-Hasan : ‘Amr bin Taghlib said, “Some property was given to the Prophet and he gave it to some people and withheld it from some others. Then he came to know that they (the latter) were dissatisfied. So the Prophet said, ‘I give to one man and leave (do not give) another, and the one to whom I do not give is dearer to me than the one to whom I give. I give to some people because of the impatience and discontent present in their hearts, and leave other people because of the content and goodness Allah has bestowed on them, and one of them is ‘Amr bin Taghlib.” ‘Amr bin Taghlib said, “The sentence which Allah’s Apostle said in my favor is dearer to me than the possession of nice red camels.”
