Surah 38. Sad, Ayah 7

I.e., "in any of the faiths prevalent in our days": an oblique reference to Christianity and its dogma of the Trinity, which contrasts with the Qur'anic concept of God's oneness and uniqueness, as well as to any other faith based on the belief in a multiplicity or multiform incarnation of divine powers (e.g., Hinduism with its triad of Brahma, Vishnu and Shiva).

 This refers either to the concept of the Trinity in Christianity or Arab polytheistic beliefs.

'Whatever may have been the case in the past', they said, 'our own immediate ancestors worshipped these idols in Makkah and why should we give them up?' Self- complacency was stronger with them than Truth; and so they call Truth "a made-up tale"! Some Commentators interpret millat akhirat to refer to the last religion preached before Islam, viz. Christianity, which had itself departed from Monotheism to Trinity.
