Mujahid reported,

Urwa bin Zubayr and I entered the mosque, and there was Abdullah bin Umar sitting beside Ayesha's apartment, while people were praying the Duha prayer in the mosque. We asked him about their prayer.He said, "An innovation."Urwa then asked him, "Abu Abdurrahman, how many times did the Messenger of Allah ﷺ perform Umrah?"He answered, "Four times, one of them in Rajab."We were reluctant to contradict him or refute him, but we heard Ayesha cleaning her teeth with a siwak inside her apartment.Urwa said, "Mother of the Believers, do you not hear what Abu Abdurrahman is saying?"She asked, "What is he saying?"He replied, "He says that the Prophet ﷺ performed Umrah four times, one of them in Rajab."She said, "May Allah have mercy on Abu Abdurrahman. The Messenger of Allah ﷺ never performed an Umrah except that he was with him, and he never performed Umrah in Rajab at all."

Sahih

عن مجاهد، قال

دخلت أنا وعروة بن الزبير المسجد، فإذا عبد الله بن عمر جالس إلى حجرة عائشة والناس يصلون الضحى في المسجد. فسألناه عن صلاتهم؟ فقال: بدعة. فقال له عروة: يا أبا عبد الرحمن، كم اعتمر رسول الله ﷺ؟ فقال: أربع عمر. إحداهن في رجب. فكرهنا أن نكذبه ونرد عليه، وسمعنا استنان عائشة في الحجرة. فقال عروة: ألا تسمعين، يا أم المؤمنين إلى ما يقول أبو عبد الرحمن؟ فقالت: وما يقول؟ قال يقول: اعتمر النبي ﷺ أربع عمر إحداهن في رجب. فقالت: يرحم الله أبا عبد الرحمن. ما اعتمر رسول الله ﷺ إلا وهو معه وما اعتمر في رجب قط.
