11. Ahmad ibn Muhammad has narrated from al-Husayn ibn Ali from Rib’iy from al-‘Ala’ ibn al-Muq‘ad who has said the following:

“I once heard abu ‘Abd Allah , say, ‘Allah, the Most Majestic, the Most Glorious, has assigned a Hijjir (persistent in doing something) angel on al-Yemaniy corner who says ‘Amen’ when you pray to Allah.’”
