It is narrated from Hazrat Sha'bi that a man from the tribe of Khath'am passed away at the place of Daqouqa. He appointed only two Christians as witnesses to his will. After Asr prayer, Abu Musa made both of them swear with these words: "By God! We have not committed any dishonesty, nor have we concealed it, nor have we altered it. Indeed, this is the will." Then he accepted the testimony of those two Christians.
