(Is it a wonder for mankind that We have inspired a man among them, saying: Warn mankind and bring unto those who believe the good tidings…) [10:2].
Said Ibn ‘Abbas: “When Allah, exalted is He, sent Muhammad, Allah bless him and give him peace, as a messenger, the unbelievers criticised him, saying: ‘Allah is too great to have a human like Muhammad as His messenger’, and so Allah, exalted is He, revealed this verse”.
