Re: Coincedence or not
Esix - - they are similar and somewhat different as well. (the arch on the top, the color, the diagonal on the door is slanted). If I would see some engraving I would be concerned.
There are about 100 similar doors in masjid nabwi. (see pic below). which is the entrance to the mosque but is not original to the masjid so nowhere near where the prophet’s grave is. All these doors were a part of the massive expansion that they did.
I have to say that Masjid Nabwi is a very pretty mosque and very high tech as well so it could be inspiring from an architectural perspective. Maybe the developer did search on ecletric doors and found this.
If you are still concerned - send some feedback to company.
