21۞ وَاذكُر أَخا عادٍ إِذ أَنذَرَ قَومَهُ بِالأَحقافِ وَقَد خَلَتِ النُّذُرُ مِن بَينِ يَدَيهِ وَمِن خَلفِهِ أَلّا تَعبُدوا إِلَّا اللَّهَ إِنّي أَخافُ عَلَيكُم عَذابَ يَومٍ عَظيمٍMajid DaryabadiAnd remember thou the brother of the Aad when We warned his people in the sandhills - and surely there have passed away warners before him and after him - saying: worship none save Allah, verily I fear for you the torment of a mighty Day.
