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.

The author said in its introduction, "Nothing offends more the Christians than to cast doubt about the doctrine of the Trinity, the fountainhead of their faith. Since I grew up as a Christian, I know by heart that it will surely injure a devout follower of Christianity something he knew as true. But to lend a blind eye when I know better is far from righteousness since I am bound by the God's Commandments to guide those mislead by the false doctrine. It is a basic right of every individual to know the truth that will lead him to the right path.
