Why don't you return to your own house and set it straight?

Why don't you return to your own house and set it straight?" (The Life of Muhammad, Cairo, 1935) Umar was furious to hear this. He immediately changed his direction from the house of Arqam to the house of his sister to investigate the allegation. In reply to his question, she gave him a discreet but evasive answer. Muhammad ibn Ishaq Umar came to the door (of the house of his sister) as Khabbab (a companion of the Prophet) was studying the Sura Taha and When the Sun is Overthrown.

The pagans used to call this reading "rubbish." When Umar came in, his sister saw that he meant mischief and hid the sheets from which they were reading. Khabbab slipped away into the house. Umar asked what was the gibberish he had heard to which she answered that it was merely conversation between them... (The Life of the Messenger of God) Umar exploded in wrath at what he thought to be a prevarication, and struck his sister in her face. The blow caused her mouth to bleed.

Umar was going to strike again but the sight of blood made him pause. He suddenly appeared to relent, and then in a changed tone asked her to show him what she was reading.

She sensed a change in him but said: "You are an unclean idolater, and I cannot allow you to touch the word of Allah." Umar immediately went home, washed himself, returned to his sister's house, read the text of Quran, and then went to Arqam's house where he bore witness to the Unity of the Creator and the Prophethood of Muhammed. Sir William Muir says that Umar's conversion to Islam took place at the close of the sixth year of Mohammed's mission.

Sir William Muir It (Umar's conversion) occurred in Dzul Hajj, the last month of the year. The believers are said now to have amounted in all to 40 men and ten women; or by other accounts, to 45 men and eleven women. (The Life of Mohammed, London, 1877) Umar was in his thirties when he became a Muslim. Muhammad Husayn Haykal At that time, Umar ibn al-Khattab was a mature man of thirty to thirty-five years of age.

(The Life of Muhammad, Cairo, 1935) Chapter 12 The Death of Khadija tul-Kubra and Abu Talib A. D. 619 The five paladins of Makka had trampled upon the covenant of the Quraysh to boycott the Bani Hashim. Thanks to their chivalry and gallantry, the Bani Hashim could return to the city, and live in their homes once again.
