Sunan Ibn Majah 2992

Muḥammad ibn al-Ṣabbāḥ narrated to us: Sufyān narrated to us. [A second chain:] ʿAlī ibn Muḥammad and ʿAmr ibn ʿAbd Allāh narrated to us; they said: Wakīʿ narrated to us. Both narrators transmitted from Dāwūd ibn Yazīd al-Zaʿāfirī, from al-Shaʿbī, from Hirm ibn Khanbash, who said: The Messenger of God (peace and blessings be upon him) said, “An ʿumrah in Ramadan is equivalent to a Hajj.”
