Musannaf Ibn Abi Shaybah 13486 — Umrah in Ramadan and what has come

Abu Bakr bin Abd al-Rahman bin al-Harith said: Sayyiduna Abu Ma'qil (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him), Sayyidah Umm Ma'qil had vowed to perform Hajj, but the means for it are not available to her." He (peace and blessings be upon him) said: "She should perform Umrah in Ramadan (its reward equals Hajj)."
