al-Baqara 2:138 — The dye of God

"The dye of God! And who is better than God at dyeing?"

صِبْغَة — root ṣ-b-gh: to dye, to steep in colour. It is used of a cloth being dipped into a dye vat.

The classical commentaries widely note that this expression was used in answer to a religious practice of the period — the registering of children into a religion by dipping them in water. On this, the sentence says: religion is not something applied on top by an operation performed once.

The word itself carries this difference. Dyeing is not smearing: what is smeared stays on the surface and wipes off; dye works into the fibre. The colour of a dyed cloth is not a coating but the cloth's own state.

This comparison belongs to the same family as the pictures we have seen elsewhere in the sūra: the calf's being drunk into the heart (2/93), sin's encompassing a person (2/81), khushūʿ's softening of the soil (2/45). In all of them the measure is the same — what stays outside, and what works inside.
