`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."
Sahih al-Bukhari Book 64, Hadith 288
← Previous Hadith Allah's Messenger (ﷺ) set out with the intention of performing `Umra, but the infidels of Quraish intervened between him and the Ka`ba, so the Prophet (ﷺ) slaughtered his Hadi (i.e. sacrificing animals and shaved his head at Al-Hudaibiya and concluded a peace treaty with them (i.e. the infidels) on condition that he would perform the `Umra the next year and that he would not carry arms against them except swords, and would not stay (in Mecca) more than what they would allow. So the Prophet (ﷺ) performed the `Umra in the following year and according to the peace treaty, he entered Mecca, and when he had stayed there for three days, the infidels ordered him to leave, and he left.

Sahih al-Bukhari Book 64, Hadith 287 Next Hadith → When Allah's Messenger (ﷺ) performed the `Umra (which he performed in the year following the treaty of Al-Hudaibiya) we were screening Allah's Messenger (ﷺ) from the infidels and their boys lest they should harm him.
