Musnad Ahmad 3924

It was narrated from Ibn Mas’ood that The Prophet (ﷺ) said: “Our Lord, may He be glorified and exalted, admires two men, a man who got up and left his mattress and blanket, and left his family and friends, to pray, and our Lord says: 'O My angels, look at My slave, he has got up and left his mattress and blanket, and left his family and friends, to pray seeking that which is with Me and fearing that which is with Me.' And (our Lord admires) a man who goes out to fight for the sake of Allah, may He be glorified and exalted; then others fled but he realized the consequences of fleeing and the consequences of returning to the fight, so he went back (and fought) until his blood was shed, seeking that which is with Me and fearing that which is with Me. And Allah, may He be glorified and exalted, says to His angels: ‘Look at My slave, he went back (and fought) seeking that which is with Me and fearing that which is with Me, until his blood was shed.’”
