Translation of a prohibitive must preserve four things: negation, person, number and gender. A generic “do not” is inadequate when the source differentiates dual, plural and feminine forms.
Word / formMeaning / explanation
لَا تَسْمَعَاdo not listen (two people).
لَا تَسْمَعُواdo not listen (men, plural).
لَا تَسْمَعِيdo not listen (one woman).
لَا يَسْمَعْنَlet those women not listen.
For Urdu-to-Arabic exercises, first identify the grammatical subject or passive patient, then form the correct person of the prohibitive.
