Sayyiduna Abu Humayd al-Sa'idi (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) appointed a man as a collector of charity. When he came after finishing his work, he said: "O Messenger of Allah (peace and blessings be upon him), this is for you, and this was given to me as a gift." He (peace and blessings be upon him) said: "Had you stayed in the house of your mother or father, would you have been given a gift?" Then the Prophet (peace and blessings be upon him) sat on the pulpit in the evening after the prayer and praised and glorified Allah. He (peace and blessings be upon him) said: "What is the matter with the collectors, that they come to us and say: 'This is yours, and these are our gifts'? Had he stayed in the house of his mother and father, then he would see whether he receives gifts or not. By Allah! Whoever accepts anything in this way will bring it on his neck on the Day of Resurrection. If it is a camel, he will bring it and it will be grumbling. If it is a cow, he will bring it and it will be lowing. If it is a goat, he will bring it and it will be bleating. I have conveyed the message." Then the Prophet (peace and blessings be upon him) raised his hands until the whiteness of his armpits could be seen.
Zayd bin Thabit (may Allah be pleased with him) also heard this along with me.
