Sahih Bukhari

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