I think we are seeing things that are not there: kind of "Lady Mondegreen" reading.
Algerean Nimchas had only 2 langets ( or are they bent quillons?) , and Zanzibarean swords had in effect 2 langets and a ring. Both would absolutely preclude "reading" the configuration of the handguard as "Allah".
If we follow the same reasoning, European D-guards would stand for " Dominus" or " Deus", and Albanian Khandjars, with their diagonally incised handles would hint at " Virgo Maria"
