The saying لَيْسَ فِيهِ شَايءِبَةُ مُلْكٍ may be from شَابَهُ “ he mixed it; ” meaning There is not in it anything [of ownership, or right of possession,] mixed therewith, though small, or however small; like as one says, لَيْسَ فِيهِ عُلْقَةٌ وَلَا شُبْهَةٌ; it being an instance of the measure فَاعِلَةٌ in the sense of the measure مَفْعُولَةٌ, as in عِيشَةٌ رَاضِيَةٌ: thus the lawyers use it. (Msb.)
