89 Preface وَقُل إِنّي أَنَا النَّذيرُ المُبينُYusuf AliAnd say: “I am indeed he that warneth openly and without ambiguity,”-1In the ministry of Al Muṣṭafā there was no mincing of matters, no compromises with evil. Evil was denounced in unambiguous terms. Mubin implies both openness and clearness, i.e., freedom from ambiguity.
