Allah says,مِمَّا خَطِييَاتِهِمْBecause of their sins,It also has been recited as; خَطَاياهُمْ(their errors.)أُغْرِقُواthey were drowned,meaning, for their numerous sins, rebellion, persistence in disbelief and opposition to their Messengers.أُغْرِقُوا فَأُدْخِلُوا نَارًاthey were drowned, then were made to enter the Fire.meaning, they will be carried from the flood of the seas to the heat of the Fire.فَلَمْ يَجِدُوا لَهُم مِّن دُونِ اللَّهِ أَنصَارًاAnd they found none to help them instead of Allah.meaning, they will have no helper, assistant, or savior who can rescue them from the punishment of Allah.This is similar to Allah's statement,لَا عَاصِمَ الْيَوْمَ مِنْ أَمْرِ اللَّهِ إِلااَّ مَن رَّحِمَThis day there is no savior from the decree of Allah except him on whom He has mercy. (11:43)وَقَالَ نُوحٌ رَّبِّ لَا تَذَرْ عَلَى الاَْرْضِ مِنَ الْكَافِرِينَ دَيَّارًا
