Mukhtasar Bukhari (Abridged) 863 — Obligation and virtue of Umrah

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "One ‘Umrah is an expiation for all the sins committed between it and the next ‘Umrah, and the only reward for an accepted Hajj is nothing but the Paradise which Allah, the Exalted, has prepared."
