(Thy Lord bringeth to pass what He willeth and chooseth…) [28:68].
The specialists of Qur’anic exegesis said: “This verse was revealed as an answer to al-Walid ibn al-Mughirah when he said, as reported by Allah, exalted is He, in the Qur’an (And they say: If only this Qur’an had been revealed to some great man of the two towns?) [43:31]. Allah, exalted is He, informed that the messengers are not sent of their own accord”.
