It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him), he says: I was on a platform in my house, a jinn would come and take (goods, etc.). I complained about this to the Noble Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: When you see him, say: "In the name of Allah! Accept the word of the Messenger of Allah." When he came, I said this to him and caught him. He said: I will not return now. So I let him go. I came to the Noble Prophet (peace and blessings be upon him) and he (peace and blessings be upon him) asked: What happened to the prisoner? I said: I had caught him, but when he promised not to come again, I let him go. He (peace and blessings be upon him) said: He will return. When he came again, I caught him and let him go two or three times; each time he would say that he would not return, and whenever I went to the Noble Prophet (peace and blessings be upon him), he (peace and blessings be upon him) would say: What did the prisoner do? I said: I catch him, and he says he will not return, so I let him go. He (peace and blessings be upon him) again said: Watch, he will return. Indeed, he came, and I caught him. This time he said: Let me go, I will teach you something by which nothing will come near you. That is Ayat al-Kursi. When I came to the Noble Prophet (peace and blessings be upon him) and told him this, he (peace and blessings be upon him) said: He is a great liar, but he has spoken the truth to you.
