Jealousy - the essence of disease, honoring of Adam (peace be upon him) and Iblis's enmity

When We asked the angels to bow before Adam, they all bowed but Iblis, who said: "Can I bow before him whom You created from clay?"

(And) said: "Look! This is what you have honoured above me! If You defer (my term) till the Day of Resurrection, I will bring his progeny into complete subjugation, barring a few."

(And God) said: "Away! Whosoever of them follows you will surely have Hell with you as requital -- an ample recompense.

Mislead any of them you may with your voice, attack them with your cavalry and soldiers on foot, share their wealth and children with them, and make promises to them." -- But the promises of Satan are nothing but deceit.

"You will surely have no power over My devotees: Your Lord is sufficient as their protector."
