The Spider - 29:14
We sent Noah to his people and he remained among them fifty years less than a thousand years. But the flood seized them because they did wrong.
The people of Noah were an unjust people who took gods besides Allah:
Prophet Noah/71:21
"Noah said, "My Lord, they have disobeyed me and followed a man whose money and children only harm him."
قَالَ نُوحٌ رَبِّ اِنَّهُمْ عَصَوْن۪ي وَاتَّبَعُوا مَنْ لَمْ يَزِدْهُ مَالُهُ وَوَلَدُهُٓ اِلَّا خَسَاراًۚ
Prophet Noah/71:23
They said, ´Do not abandon your gods. Do not leave Vedd, nor Suva, nor Yegus, nor Yeuk, nor Nesr.
وَقَالُوا لَا تَذَرُنَّ اٰلِهَتَكُمْ وَلَا تَذَرُنَّ وَداًّ وَلَا سُوَاعاًۙ وَلَا يَغُوثَ وَيَعُوقَ وَنَسْراًۚ
Prophet Noah/71:24
They have led many astray. So increase the confusion of the wrongdoers.
وَقَدْ اَضَلُّوا كَث۪يراًۚ وَلَا تَزِدِ الظَّالِم۪ينَ اِلَّا ضَلَالاً
