Foundations

What is tawḥīd? The core of Islamic belief, explained.

Tawḥīd — the oneness of Allah — is the foundation of every other Islamic doctrine. What the scholars said about it is far richer than the one-line definition most Muslims grow up with.

4 passages from 1 book in the library

Where the answer comes from

The classical approach.

These passages are drawn from 1 book by Imam al-Ghazali — part of the classical Sunni tradition that carries over a thousand years of reflection on the Qurʾān, the authentic Sunnah, and the consensus of the early community. Nothing below is a paraphrase. The words are the scholars' own, translated from the original Arabic manuscripts.

Read them closely. If a passage doesn't sit right, open the full book in the library and listen to the chapter around it. Context in the classical tradition is everything.
