Tawhid Quotes

Sins are like chains and locks preventing their perpetrator from roaming the vast garden of tawhid and reaping the fruits of righteous actions. (Ibn Taymiyyah)
Indeed, you should not desire to weigh with the intellect the issues of Tawhīd and the Hereafter; the reality of Prophethood; the reality of divine attributes and every other thing beyond the scope of the intellect, for such a desire is futile. An example of this would be a man who has a scale used for weighing gold suddenly desiring to weigh mountains with it! This does not mean that the scale is wrong in its measures; rather, the intellect has a limit it cannot surpass and a boundary it cannot transcend. View quote
Ibn Khaldun
Knowledge of God comprises three kind: Theological, philosophical and mystical. Theological knowledge concerns with tawhid or unification. Philosophical knowledge deals with the concept of Ultimate Truth, reached through reason. Mystical knowledge is the knowledge of the Essence of God. It is attained by the saints after mushahada or the contemplation on God in their illuminated hearts. View quote
