Why, in Istanbul, do Muslims attend a church and write prayer intentions? This article explores a kind of religious poaching through three levels of observation: divine otherness, the otherness of the place represented by the church, and family and social otherness.

Far from being linked to “irenicist” dynamics, hospitality, syncretism or, conversely, intolerance, it is in fact about evading difference, enjoying it without recognizing it. Religious poaching is based on a practice of indifference.
