We have created you from a male and a female, and made you
into nations and tribes, that you may know one another. Verily, the most
honorable of you with God is that who has At-Taqwa. Verily, God is All-
knowing, All-Aware. [The Quran 49:13]
Is taqwa righteousness? Many translators have used righteousness as the equivalent to TAQWA. Generally so and it is not wrong. I think TAQWA is more than that.
Since TAQWA has been specified by GOD as the measure of honour, why is it not our primary mission? Thus this search.
The tool and source will be the Revelations.
