Surah 21. Al-Anbiya, Ayah 70

Inasmuch as Abraham forsook - as shown in the next verse - his homeland, and thus abandoned his people to their spiritual ignorance.

As they could not get rid of him by open punishment, they tried secret plans, but were foiled throughout. It was not he that lost, but they. On the contrary he left them and prospered and became the progenitor of great peoples.
