Prophet Hud - 11:90
Ask forgiveness from your Lord, then repent to Him. Surely my Lord is Most Merciful, Loving.
The sins of Shu'ayb's people, the Median people, which required forgiveness and repentance:
Prophet Hud/11:84
"And to Median We sent their brother Shu´ayb. He said: "O my people, serve Allah, you have no god but Him. Do not keep the measure and the weighing deficient. I see you in prosperity and I fear for you the torment of an encompassing Day."
وَاِلٰى مَدْيَنَ اَخَاهُمْ شُعَيْباًۜ قَالَ يَا قَوْمِ اعْبُدُوا اللّٰهَ مَا لَكُمْ مِنْ اِلٰهٍ غَيْرُهُۜ وَلَا تَنْقُصُوا الْمِكْيَالَ وَالْم۪يزَانَ اِنّ۪ٓي اَرٰيكُمْ بِخَيْرٍ وَاِنّ۪ٓي اَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ مُح۪يطٍ
Prophet Hud/11:85
O my people, measure and weigh exactly with justice. Do not shortchange the people and do not commit evil by corrupting the earth.
وَيَا قَوْمِ اَوْفُوا الْمِكْيَالَ وَالْم۪يزَانَ بِالْقِسْطِ وَلَا تَبْخَسُوا النَّاسَ اَشْيَٓاءَهُمْ وَلَا تَعْثَوْا فِي الْاَرْضِ مُفْسِد۪ينَ
Prophet Hud/11:87
"They said: "Shu´ayb, does your prayer require us to give up what our ancestors used to serve or to turn our trade as we wish? You are indeed mild-tempered and wise."
قَالُوا يَا شُعَيْبُ اَصَلٰوتُكَ تَأْمُرُكَ اَنْ نَتْرُكَ مَا يَعْبُدُ اٰبَٓاؤُ۬نَٓا اَوْ اَنْ نَفْعَلَ ف۪ٓي اَمْوَالِنَا مَا نَشٰٓؤُ۬اۜ اِنَّكَ لَاَنْتَ الْحَل۪يمُ الرَّش۪يدُ
