Imran b. al-Husain (Allah be pleased with him) said:Know well that Allah's Messenger (ﷺ) combined 'Hajj and 'Umra, and nothing was revealed in the Book (to abrogate it), and the Messenger of Allah (ﷺ) too did not forbid us from (combining) them. And whatever a person said was out of his personal opinion
