Musnad Ahmad 32:2085

'Affan narrated to us, Hammad narrated to us, Thabit informed us, from Anas: "A man asked the Prophet, may Allah bless him and grant him peace, so he gave him sheep between two mountains. He went to his people and said: 'O my people, embrace Islam, for by Allah, Muhammad gives a gift of one who does not fear poverty.' And a man would come to the Messenger of Allah, may Allah bless him and grant him peace, desiring nothing but the world, yet he would not reach the evening until his religion was more beloved to him—or more dear to him—than the world and all that is in it."
