"Must be related to Arab. wzm 'to pay a debt; to join a small piece of something to what is similar to it" (LA 12 756), so sparsely attested that one may wonder whether it is autochtonous in Arabic. A borrowing from Arabic into MSA is, in this case, quite unlikely" (Kogan 2015:576)
The origin of Proto-MSA *šitim- ‘heaven’ is enigmatic: an eventual connection with PS *šamāy- is difficult to avoid (Bittner 1909:42), but the underlying phonological and/or structural development has never been convincingly established (none of the hypotheses listed by Leslau in LS 78 is persuasive).
one of the four widespread designations of camel in individual languages, the similarity between these designations must be due to diffusion from an Arabian source

Very scarce attestation: Arb. and ESA only; possibility of an inter-borrowing cannot be ruled out. Seems to be supported by Afras.
