"Let His love be a storehouse of treasure for your souls, on the Day when naught else but Him shall profit you, the Day when every pillar shall tremble, when the very skins of men shall creep, when all eyes shall stare up with terror."

"Arise, O wayfarer in the path of the Love of God, and aid thou His Cause. Say: Barter not away this Youth, O people, for the vanities of this world or the delights of heaven. By the righteousness of the one true God! One hair of Him excelleth all that is in the heavens and all that is on the earth. Beware, O men, lest ye be tempted to part with Him in exchange for the gold and silver ye possess. Let His love be a storehouse of treasure for your souls, on the Day when naught else but Him shall profit you, the Day when every pillar shall tremble, when the very skins of men shall creep, when all eyes shall stare up with terror. Say: O people! Fear ye God, and turn not away disdainfully from His Revelation. Fall prostrate on your faces before God, and celebrate His praise in the daytime and in the night season."
