What did the Prophet Muhammad (peace be upon him) do during his four 'Umra pilgrimages?
 Narrated Mujahid:                     Urwa bin Az-Zubair and I entered the Mosque (of the Prophet) and saw `Abdullah bin `Umar sitting near the dwelling place of Aisha and some people were offering the Duha prayer. We asked him about their prayer and he replied that it was a heresy. He (Urwa) then asked him how many times the Prophet had performed `Umra. He replied, 'Four times; one of them was in the month of Rajab." We disliked to contradict him. Then we heard `Aisha, the Mother of faithful believers cleaning her teeth with Siwak in the dwelling place. 'Ursa said, "O Mother! O Mother of the believers! Don't you hear what Abu `Abdur Rahman is saying?" She said, "What does he say?" 'Urwa said, "He says that Allah's Apostle performed four `Umra and one of them was in the month of Rajab." `Aisha said, "May Allah be merciful to Abu `Abdur Rahman! The Prophet did not perform any `Umra except that he was with him, and he never performed any `Umra in Rajab."
