مَسْتُورٌ

حِجَابًا مَسْتُورًا, in the Qur'an, 17:47, means A veil covered by another veil; implying the thickness of the veil: (S:) or مستورا is here of the measure مَفْعُولٌ in the sense of the measure فَاعِلٌ, like مَأْتِيًّا in the Qur'an, 19:62, (S, M,) which some say is the only other instance of the kind; (TA;) and Th explains it as signifying preventing, or hindering, or obstructing; and says that it is of the measure مَفْعُولْ because the veil itself is hidden from man. (M.)
