Mujahid reported: I and 'Urwa bin Zubair entered the mosque and there found 'Abdullah bin 'Umar sitting near the apartment of A'isha and the people were observing the forenoon prayer (when the sun had sufficiently risen). We asked him about their prayer, and he said: It is bid'a (innovation), Urwa said to him: Abdul Rahman, how many 'Umrahs had Allah's Messenger ( صلی اللہ علیہ وسلم ) performed? He said: Four 'Umrahs, one he performed during the month of Rajab. We were reluctant either to belie him or reject him. We heard the noise of brushing of her teeth by 'A'isha in her apartment. 'Urwa said: Mother of the Faithful, are you not hearing what Abi 'Abdul Rahman is saying? She said: What is he saying? Thereupon he ('Urwa) said: He (Ibn 'Umar) states that Allah's Apostle ( صلی اللہ علیہ وسلم ) performed four 'Umrahs and one of them during the month of Rajab. Thereupon she remarked: May Allah have mercy upon Abu 'Abdul Rahman. Never did Allah's Messenger ( صلی اللہ علیہ وسلم ) perform 'Umrah in which he did not accompany him, and he (Allah's Apostle) ( صلی اللہ علیہ وسلم ) never performed 'Umrah during the month of Rajab.
