Hadith 883

Imam Abu Bakr (may Allah have mercy on him) says that I have already dictated on previous pages that the Noble Prophet (peace and blessings be upon him) said: "When any one of you is praying, he should not allow anyone to pass in front of him, and if that person refuses (to stop), then he should fight him, for he is a devil."
