I am from Egypt and thinking to myself now: what does that even mean? it doesn't make a lot of sense to me but translating it, it should go
"He will throw a tile"...or "I will throw a tile"
"and write on it...Mohamed Elgabr, the hero of our nation tombstone"
Does that make sense?? Not to me anyways
Mohamed Elgabr is a name but I think there is something wrong in the sentence.
