Best Speech

Allah has sent down the best of speech, a Book consistent in its teachings, with alternating themes that make the hearts of those who fear their Lord tremble.

22:24They are guided unto gentle speech; they are guided unto the path of the Glorious One.

39:23Allah hath (now) revealed the fairest of statements, a Scripture consistent, (wherein promises of reward are) paired (with threats of punishment), whereat doth creep the flesh of those who fear their Lord, so that their flesh and their hearts soften to Allah's reminder. Such is Allah's guidance, wherewith He guideth whom He will. And him whom Allah sendeth astray, for him there is no guide.
