The ruling on performing 'Umrah after completing the rites of Hajj.

The Shaykh : From here, we take a subtle point: what pilgrims do today by intentionally performing 'Umrah after completing the rites of Hajj, by leaving Makkah to al-Tan'īm, which is called today "A'ishah's Mosque," has no basis in the Sunnah in the first place. It is contrary to what we establish, which is that the better course is to make things easy if possible. Therefore, the Shari'ah commands the pilgrim to perform 'Umrah before Hajj: he performs 'Umrah in one of the months of Hajj, exits the state of ihram after the 'Umrah while in Makkah, then resumes ihram on the eighth day while in Makkah—ihram for Hajj—and continues with the acts of Hajj. When he performs the Tawaf of Ifadah, his Hajj is complete, and there is no 'Umrah after that. What the majority of people do by performing 'Umrah after Hajj is not prescribed except for a specific group of people: women, first, and not all of them, but only the menstruating women. This refers to one whose situation is like that of A'ishah (may Allah be pleased with her), who performed the 'Umrah of Hajj but menstruation prevented her from performing Tawaf around the House, so she did not perform 'Umrah due to a valid legal excuse. She is the one who may perform 'Umrah after Hajj.
Therefore, by deduction from this authentic hadith, we call the 'Umrah performed after Hajj "the 'Umrah of the menstruating woman." That is, the menstruating woman who was unable to perform 'Umrah before Hajj is the one who performs 'Umrah after Hajj. As for the woman who is in a state of purity, she may not perform 'Umrah after Hajj; rather, she must perform 'Umrah before Hajj. It is even more so for the man, whom Allah has preferred over women by not making him menstruate: why should he imitate the menstruating women by performing the 'Umrah of the menstruating women? This is something the majority of people overlook. Therefore, one hundred thousand or more people performed Hajj with the Prophet (peace and blessings be upon him), and not one of them performed 'Umrah after Hajj, absolutely not. Nor did the women, except only A'ishah (may Allah be pleased with her) with the excuse you have heard.
The point of this is that at the end of this hadith, those for whom the love of Allah (Mighty and Majestic) is obligatory and due are those who exchange money with one another, even if it is a small amount. This is because, as you know, the reward is proportional to the hardship when there is no presence or ability, and because of what was previously mentioned of his saying (peace and blessings be upon him): .
