Is it obligatory to perform `Umrah upon entering Makkah in an errand to serve the guests of The Most-Merciful?

Q 13: Is it obligatory to perform `Umrah (lesser pilgrimage) upon entering Makkah in an errand to serve the guests of The Most-Merciful? If `Umrah is obligatory and the intention is determined, should Ihram (ritual state for Hajj and `Umrah) be assumed from the Miqat (site for entering the ritual state for Hajj and `Umrah)?

A: Whoever goes to Makkah and has never performed the `Umrah of Islam should assume Ihram for `Umrah from the Miqat that they pass by on their way and (Part No. 10; Page No. 19) they should perform the rituals of `Umrah. As for a person who has performed `Umrah previously, it is not obligatory on them. However, if they intend to perform `Umrah during their travel, they should assume Ihram for `Umrah from the Miqat, and it is impermissible for them to pass it without Ihram. But if they intended to perform `Umrah after they had passed the Miqat, they should assume Ihram from the place where they intended to perform `Umrah, i.e., outside the Al-Haram (all areas within the Sacred Sanctuary of Makkah). And if they intend to perform `Umrah while they are inside the Al-Haram, they have to go outside the Al-Hil (all areas outside the Sacred Sanctuary of Makkah) and assume the state of Ihram for `Umrah from it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
