Surah 43. Az-Zukhruf, Ayah 29

I.e., God did not impose on them any moral obligations before making the meaning of right and wrong clear to them through a revealed message. Primarily, this is an allusion to the pagan contemporaries of the Prophet, and to the prosperity which they had been allowed to enjoy for a long time (cf. 21:44 ); in its wider sense, however, this passage implies that God would never call people to task for any wrong they may have done so long as they have not been clearly shown how to discriminate between good and evil (cf. {6:131-132}).

Note the first person singular, as showing Allah's personal solicitude and care for the descendants of Abraham in both branches. The context here refers to the prosperity enjoyed by Makkah and the Makkans until they rejected the truth of Islam when it was preached in their midst by a messenger whose Message was as clear as the light of the sun.
