Musnad Ahmad 6295

Translation

✧ Urwah ibn al-Zubayr asked Ibn Umar, "In which month did the Messenger of Allah ﷺ perform Umrah?" He replied, "In the month of Rajab." Aisha overheard and Ibn Zubayr asked her and informed her of what Ibn Umar said. She said, "May Allah have mercy on Abu 'Abd al-Rahman, the Messenger of Allah ﷺ never performed Umrah except in the month of Dhul-Hijjah."
