Muhammad bin Zayd bin Abdullah bin Umar (may Allah have mercy on him) said: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) recited this verse: "He has not placed upon you any hardship in religion." [Surah al-Hajj: 78]
Then he said: Call for me a man from Banu Mudlij, for they are the (true) Arabs. Then Sayyiduna Umar (may Allah be pleased with him) asked: What does "haraj" mean among you? He said: Narrowness.
