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 ﷺ 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'.Urwa 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 Messenger ﷺ 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 ﷺ did not perform any 'Umra except that he was with him, and he never performed any 'Umra in Rajab".
