Hazrat Jarir says that I said to my sons: O my sons! When the collector of Zakat comes to you, do not hide anything from your wealth from him.

It is narrated from Hazrat Abu Uthman that Hazrat Abu Hurairah said: When the collector of Zakat comes to you and says, "Give your Zakat," then you should (immediately) give your Zakat. And if he accepts it, that is very good, and if he refuses, then turn your back on him and do not argue with him, and say thus: "O Allah! I hope for reward from You for what he has taken from me," and do not curse or reproach that person.

It is narrated from Hazrat Jarir that the Holy Prophet (peace and blessings be upon him) said: When the collector of Zakat returns from you, he should return in such a state that he is pleased with you.

Hazrat Jabir bin Abdullah (may Allah be pleased with him) narrates from his father that the Noble Prophet (peace and blessings be upon him) said: Soon, disliked riders will come to you, but when they come to you (to collect zakat), welcome them and make things easy for them, and leave among them that thing in which they exceed. So if they act justly, it is for their own selves, and if they act unjustly, then its burden is upon them. And you should try to please them; indeed, the completion of your zakat depends on their satisfaction, and they should also supplicate for you.

Hazrat Dahhak states that when Hazrat Umar bin Khattab came to know that (someone's) wealth had been concealed from Zakat, he would collect five times that amount.

Hazrat Ubaidullah bin Razeeq narrates that I heard Hasan say that the Messenger of Allah, peace and blessings be upon him, said: Whoever has paid the zakat on his wealth has fulfilled the right that was due from him, and whoever gives more, it is better for him (the reward for giving more is for him alone).

It is narrated from Hazrat Ikrimah that Hazrat Ibn Abbas (may Allah be pleased with them both) said: Whoever has paid the zakat on his wealth, then if he does not give charity beyond that, there is no sin upon him.
