Ursa 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 (Ursa) then asked him how many times the Prophet 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. 'Ursa said, "O Mother! O Mother of the believers! Don't you hear what Abu `Abdur Rahman is saying?" She said, "What does he say?" 'Ursa said, "He says that Allah's Apostle 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 did not perform any `Umra except that he was with him, and he never performed any `Umra in Rajab."

Narrated 'Ursa bin Az−Zubair: I asked `Aisha (whether the Prophet had performed `Umra in Rajab). She replied, "Allah's Apostle never performed any `Umra in Rajab."
- Sahih Bukhari, Vol-3, hadith-5
I asked Anas how many times the Prophet had performed `Umra. He replied, "Four times.
1. `Umra of Hudaibiya in Dhi−l−Qa'da when the pagans hindered him;
2. `Umra in the following year in Dhi−l−Qa'da after the peace treaty with them (the pagans);
3. `Umra from Al−Ja'rana where he distributed the war booty."
I think he meant the booty (of the battle) of Hunain. I asked, "How many times did he perform Hajj?" He (Anas) replied, "Once. "
