" ... God will bring everything to light, though it were but the weight of a grain of mustard-seed ..."

"The time is at hand when whatsoever lieth hid in the souls and hearts of men will be disclosed. This Day is the Day whereof Luqmán 1 spoke unto his son, the Day which the Lord of Glory announced and with which He acquainted Him Who was His Friend (Muḥammad) through these, His words—exalted be He:—“O my son! Verily, God will bring everything to light, though it were but the weight of a grain of mustard-seed, and hidden in a rock or in the heavens or in the earth; for God is Subtile, informed of all.” This Day the deceitful of eye, and all that men’s breasts conceal, are made known and laid bare before the throne of His Revelation. Nothing whatsoever can escape His knowledge. He heareth and seeth, and He, in truth, is the All-Hearing, the All-Seeing. How very strange that they discern not between the trustworthy and the treacherous!"
