Ibn Rajab al-Hanbali This is a treatise we have written concerning humility (Khushu') and the hearts meekness and breaking (inkisar) before the Lord. The basic meaning of Khushu', is the softness of the heart, its being gentle, still, submissive, broken, and yearning. When the heart is humble, so too is the hearing, seeing, heard, and face; indeed all the limbs and their actions are humbled, even speech. The source of the Khushu, that takes place in the heart is the gnosis of Allah's greatness, magnificence, and perfection.
