Hazrat Zaid bin Wahb (may Allah have mercy on him) narrates that two men came to Hazrat Abdullah bin Masood (may Allah be pleased with him). Then one of them said: How do you recite this verse? So Hazrat Abdullah (may Allah be pleased with him) asked him: Who taught you this verse? He said: Hazrat Abu Hakeem Al-Muzani did. And he (may Allah be pleased with him) asked the other: Who taught you this verse? He said: Hazrat Umar (may Allah be pleased with him) taught me. He (may Allah be pleased with him) said: You recite as Hazrat Umar (may Allah be pleased with him) taught you. Then he began to weep until his tears fell upon the pebbles. Then he said: Indeed, Hazrat Umar (may Allah be pleased with him) was a strong and firm fortress of Islam, in which Islam entered and did not leave from it. So when Hazrat Umar (may Allah be pleased with him) passed away, a breach appeared in that fortress, so Islam left from it and did not enter it again.
