Hadith 4613
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The one who participates in battle in the way of Allah, the one who performs Hajj to the House of Allah, and the one who performs Umrah are the guests of Allah. Allah Almighty has called them, and they come in response to His call."
