It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Soon you will conquer the land of Egypt, and in that region the word "qirat" is used. When you conquer it, treat its inhabitants well, for they have a covenant and kinship with you. So, when you see two men fighting over a brick's place there, leave that place. Then I saw Abdur Rahman bin Sharjeel and his brother Rabee'ah fighting each other over a brick's place, so I left that place.
