Then we heard `Aisha brushing her teeth whereupon `Urwa said, O mother of the believers! Don't you hear what Abu `Abdur-Rahman is saying? He is saying that the Prophet performed four `Umra, one of which was in Rajab. `Aisha said, The Prophet did not perform any `Umra but he (i.e. Ibn `Umar) witnessed it. And he (the Prophet ) never did any `Umra in (the month of) Rajab.
