Narated By AbudDarda' : The Prophet (pbuh) said: If anyone takes land by (paying) its jizyah, he renounces his immigration; and if anyone takes off the disgrace of an unbeliever from his neck he turns away his back from Islam. He (the narrator) said: Thereafter Khalid ibn Ma'dan heard this tradition from me, and he said: Has Shubayb narrated it to you? I said: Yes. He said! When you come to him, ask him to write this tradition to me. He said: He then wrote it for him. When I came, Khalid ibn Ma'dan asked me for the paper and I gave it to him. When he read (the paper), he abandoned the lands he had in his possession the moment he heard this.
