question #3 Sahih Muslim 1241, Book 15, Hadith 222 : How has the practice of ‘Umra been integrated into Hajj until the Day of Resurrection?

This is the ‘Umra of which we have taken advantage. So he who has not the sacrificial animal with him should get out of the state of Ihram completely, for ‘Umra has been incorporated in Hajj until the Day of Resurrection,
