Does placing wooden beams resting on a wall serve to strengthen one party's claim in a dispute over the wall's ownership?

The dominant opinion among our companions and that of Al-Shafi'i holds that placing wooden beams does not strengthen a party's claim. This is because permitting a neighbor to rest beams is a matter of mutual concession (*tasamuh*), and a narration advises against preventing it. Moreover, this right of resting beams is considered something that must be permitted, so it does not serve to tip the scale of proof, similar to leaning one's belongings or plastering/decorating the wall. The evidence cited against utilizing this is that it is a common courtesy, not an established right proving ownership.

The view held by Malik suggests that placing beams does strengthen the claim because the owner is utilizing the wall by placing their property upon it, analogous to the builder or the sower in land. This view is supported by the narration prohibiting prevention, though that prohibition does not negate the beam placement as evidence of entitlement. A contrasting position held by the companions of Abu Hanifa states that a single beam does not strengthen the claim because a wall is not built for a single beam, but two beams do strengthen the claim because the wall is built to support both. The opposing scholars argue that since the beam rests upon the wall, its quantity, whether small or large, should be equal in evidentiary weight to actual construction.
