Jabir said:
"When a man enters his house or goes to bed, an angeland shaytan hasten to him. The angel says, 'Seal it with good!' The Shaytansays, 'Seal it with evil.' If he praises Allah and remembers Him, he chasesthe shaytan away and spends the night with him guarding him. When he wakesup, the angel and shaytan hasten to him and say the same thing. If he mentionsAllah and says, 'Praise be to Allah, who keeps firm hold of the heavensand earth, preventing them from vanishing away. And if they vanished noone could then keep hold of them. Certainly He is Most Forbearing, Ever-Forgiving.'(35:41)Praise be to Allah who holds back the sky preventing it from fallingon the earth, except by His permission. Allah is All-Compassionate to mankind,Most Merciful.' (22:63) If he dies, he dies a martyr, If he gets upand prays, he prays in virtue.'"
