حَدَّثَنِي عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ مُجَاهِدٍ، قَالَ دَخَلْتُ أَنَا وَعُرْوَةُ بْنُ الزُّبَيْرِ الْمَسْجِدَ، فَإِذَا عَبْدُ اللَّهِ بْنُ عُمَرَ ـ رضى الله عنهما ـ جَالِسٌ إِلَى حُجْرَةِ عَائِشَةَ ثُمَّ قَالَ كَمِ اعْتَمَرَ النَّبِيُّ صلى الله عليه وسلم قَالَ أَرْبَعًا ‏ end actual hadith container 7‏ ثُمَّ سَمِعْنَا اسْتِنَانَ، عَائِشَةَ قَالَ عُرْوَةُ يَا أُمَّ الْمُؤْمِنِينَ أَلاَ تَسْمَعِينَ مَا يَقُولُ أَبُو عَبْدِ الرَّحْمَنِ إِنَّ النَّبِيَّ صلى الله عليه وسلم اعْتَمَرَ أَرْبَعَ عُمَرٍ‏.‏ فَقَالَتْ مَا اعْتَمَرَ النَّبِيُّ صلى الله عليه وسلم عُمْرَةً إِلاَّ وَهْوَ شَاهِدُهُ، وَمَا اعْتَمَرَ فِي رَجَبٍ قَطُّ‏.‏

Narrated Mujahid: `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 (PBUH) 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 (PBUH) did not perform any `Umra but he (i.e. Ibn `Umar) witnessed it. And he (the Prophet (PBUH) ) never did any `Umra in (the month of) Rajab." Translation Not Available
