(Al-Hijr) 15 : 70
قَالُوا أَوَلَمْ نَنْهَكَ عَنِ الْعَالَمِينَ
They said: "Have we not forbidden you about the people?"
Like every transgressed people obstructed their Messenger from propagating Adhikr, Prophet Looth’s people also obstructed him as explained in verses 7: 82-84. See explanation 7: 163-166.
