[Pooya/Ali Commentary 21:27] The prophets of Allah were His servants raised to honour. They neither spoke nor acted, at any time, of their own will. They said and acted (in all things) by Allah's command. This verse proves that all the prophets and messengers of Allah were infallible because whatever they said or did was in fact Allah's word or action. Isa said: "I do not speak on my own authority, but the Father who sent me has Himself commanded me what to say and how to speak" (John 12: 49) According to verse 136 of al Baqarah, Islam respects, honours and reveres all the prophets of Allah.
