Al-Farrā’ said regarding His words:
“So say, ‘I have submitted myself wholly to Allah.’”
[Surah Āl Imrān: 20]
It means: “I have made my deeds sincere.”
Al-Zajjāj said: “I have directed my worship to Allah.” The meaning is as they stated, and its interpretation has already been explained elsewhere.
This is the meaning around which the Quran revolves.

It is stated in a hadith:
“Whoever commands what is right and forbids what is wrong should be thoroughly knowledgeable (2) about what he commands, thoroughly knowledgeable (3) about what he forbids, gentle in what he commands, [gentle regarding what he
