3 عَامَلَهُ مُدَاهَرَةٌ ذ and دِهَارًا is like مُشَاهَرَةً [i. e. it means He made an engagement, or a contract, or bargain, with him to work, or the like, for a long period, or for a constancy; like as مُشَاهَرَةً means “for a month”]. (K.) And in like manner one says, اِسْتَأْجَرَهُ مُدَاهَرَةً and دِهَارًا [ He hired him for a long period, or for a constancy ]. (Lh, TA.)
