مَرَرْتُ بِعُمَرٍ آخَرَ — “I passed another ʿUmar.”
عُمَرٍ: genitive triptote with kasrah and tanwīn in its indefinite use. آخَرَ: genitive adjective agreeing in case, but a diptote in its own right, so its genitive marker is fatḥah.
Agreement in case does not require identical visible case markers.
