´Urwah said:` Ibn Umar was asked: In which month did the Messenger of Allah perform Umrah? He said: 'During Rajab.' So Aishah said: 'The Messenger of Allah did not perform Umrah except that he was with him - meaning Ibn Umar - and he did not ever perform Umrah in the month of Rajab.'"
Shaykh Dr. Abdur Rahman Freywai
Commentary: 1؎ : In one narration of Muslim, it is mentioned that when Ibn Umar heard this statement of Aisha radi Allahu anha, he remained silent and did not say anything. From this, it is understood that the matter was unclear to him— either he had forgotten, or he had become doubtful. For this reason, he did not give any response to the statement of Umm al-Mu’minin. In this regard, the correct position is that of Umm al-Mu’minin, that the Prophet sallallahu alayhi wa sallam did not perform any ‘umrah in the month of Rajab.
