Sa'id bin al-Musayyib (may Allah have mercy on him) said: I heard a phrase from Umar bin al-Khattab (may Allah be pleased with him) that no one besides me who heard it remains alive. I heard him say, when he saw the House: 'Allahumma anta al-salam wa minka al-salam, hayyina rabbana bil-salam' (O Allah, You are Peace and from You alone comes peace; our Lord, let us live in peace).
