Is Umrah like Hajj in reward, forgiveness, and returning as if born anew? And does Umrah in Ramadan have a special reward?

The reward for 'Umrah does not equate to the reward for Hajj, for Hajj is definitively superior and a pillar of Islam, whereas the obligation of 'Umrah is a matter of scholarly disagreement. Drawing near to Allah through obligatory acts is more beloved to Him. Texts regarding the virtue of Hajj include: "Hajj Mabrur has no reward but Paradise," and "Whoever performs Hajj and does not engage in sexual intimacy or commit sins, returns from his sins as on the day his mother gave birth to him." As for 'Umrah, it is mentioned that it only expiates sins: "'Umrah to 'Umrah is an expiation for what is between them," and "Continue to perform Hajj and 'Umrah, for they remove poverty and sins."

The one who repents from a sin is like one who has no sin. There is a difference of opinion regarding Hajj expiating major sins from which the servant has not repented.

The virtue of 'Umrah in Ramadan is immense, due to the saying of the Prophet, peace and blessings be upon him: "An 'Umrah in Ramadan is equal to a Hajj," and it was said in one narration: "with me." This does not mean that it equals the reward of Hajj in every respect. Ishaq ibn Rahawayh likened this hadith to the hadith, "Whoever recites 'Qul Huwa Allahu Ahad,' he has recited one-third of the Qur'an." Some scholars interpreted this hadith as being specific to that woman who wished to perform Hajj with the Prophet, peace and blessings be upon him, as she was unable to do so, so he informed her of what would stand in its place. It does not mean that one's 'Umrah is equal to a complete Hajj with him, for a complete Hajj is superior.
