Surah Al-Anbiya Verse 49

2710 Note the three kinds of fear mentioned in 21:48-49. Taqwa is the fear of running counter to the will of Allah; it is akin to the love of Him; for we fear to offend those we love; it results in right conduct, and those who entertain it are "those who would do right". Then there is Khashyah, the fear of Allah, lest the person who entertains it may be found, in his inmost thoughts, to be short of the standard which Allah wished for him; this is also righteous but in a less high degree than Taqwa which is akin to love. And thirdly, there is the fear of consequences on the Day of Judgement (ishfaq); this also may lead to righteousness, but is on a still lower plane. Perhaps the three correspond to the Criterion, the Light, and the Message (or Warning) of the last verse.
