the Prophet sent a collector and he came to a man who brought him a slim, recently-weaned camel. The Prophet said: "We sent to Zakah collector of Allah and His Messenger, and so-and-so gave him a slim, recently-weaned camel. O Allah, do not bless him nor his camels!" News of that reached the man, so he came with a beautiful she-camel and said: "I repent to Allah and to His Prophet. " The Prophet said: "O Allah, bless him and his camels!"
