Sahih Bukhari: Hadith 4083

`Urwa and I entered the Mosque and found `Abdullah bin `Umar sitting beside the dwelling place of `Aisha. `Urwa asked (Ibn `Umar), "How many `Umras did the Prophet (ﷺ) perform?" Ibn `Umar replied, "Four, one of which was in Rajab." 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 (ﷺ) did not perform any `Umra but he (i.e. Ibn `Umar) witnessed it. And he (the Prophet (ﷺ) ) never did any `Umra in (the month of) Rajab."
