Would the plural of <ustād> be <ustāzah>? Here are my planned sentences. I'd like to know if it sounds OK. The "X SaHib" is the program head and he has a team of instructors that work with him as well. <'aalī janāb X SāHib aur tamām ustāzah. xidmat me.n ādāb pesh kartā hū.n. umīd hai keh mizāj e girāmī baxer ho.nge>.
