It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that he was travelling with the Messenger of Allah (peace and blessings be upon him) on a journey. He asked him (peace and blessings be upon him) about some matter, but he (peace and blessings be upon him) gave him no answer. He asked again, and still he (peace and blessings be upon him) did not answer. Then he asked a third time, but he (peace and blessings be upon him) remained silent. At this Sayyiduna Umar (may Allah be pleased with him) said (reproaching himself): "O Umar, may your mother be bereaved of you! You asked the Messenger of Allah (peace and blessings be upon him) three times, and he (peace and blessings be upon him) gave you no answer." He relates: Then I spurred my camel on and went ahead of the people, and I feared that some verse of the Qur'an might be revealed about me (because of this persistence). Only a little while had passed when I heard a caller calling out. I presented myself before the Messenger of Allah (peace and blessings be upon him) and said that I feared that Qur'an might have been revealed concerning me. Then I greeted him (peace and blessings be upon him) with salam, and the Messenger of Allah (peace and blessings be upon him) said: "Tonight a surah has been revealed to me that is more beloved to me than everything on which the sun rises." Then he (peace and blessings be upon him) recited these verses: "Indeed, We have granted you a clear victory, so that Allah may forgive you your former and later shortcomings."
