It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Allah has made the truth flow upon Umar's heart and tongue." Sayyiduna Ibn Umar (may Allah be pleased with them both) says that whenever any matter was presented before the people and the people had one opinion and Sayyiduna Umar (may Allah be pleased with him) had another opinion, then the Noble Qur'an would be revealed close to the opinion of Sayyiduna Umar (may Allah be pleased with him).
