أُبَلِّغُكُمْ رِسَالاَتِ رَبِّي وَأَنصَحُ لَكُمْ وَأَعْلَمُ مِنَ اللّهِ مَا لاَ تَعْلَمُونَ
"I but fulfil towards you the duties of my Lord's mission: Sincere is my advice to you, and I know from Allah something that ye know not.

7:79
فَتَوَلَّى عَنْهُمْ وَقَالَ يَا قَوْمِ لَقَدْ أَبْلَغْتُكُمْ رِسَالَةَ رَبِّي وَنَصَحْتُ لَكُمْ وَلَكِن لاَّ تُحِبُّونَ النَّاصِحِينَ

فَتَوَلَّى عَنْهُمْ وَقَالَ يَا قَوْمِ لَقَدْ أَبْلَغْتُكُمْ رِسَالاَتِ رَبِّي وَنَصَحْتُ لَكُمْ فَكَيْفَ آسَى عَلَى قَوْمٍ كَافِرِينَ
So Shu'aib left them, saying: "O my people! I did indeed convey to you the messages for which I was sent by my Lord: I gave you good counsel, but how shall I lament over a people who refuse to believe!"

وَلاَ يَنفَعُكُمْ نُصْحِي إِنْ أَرَدتُّ أَنْ أَنصَحَ لَكُمْ إِن كَانَ اللّهُ يُرِيدُ أَن يُغْوِيَكُمْ هُوَ رَبُّكُمْ وَإِلَيْهِ تُرْجَعُونَ
"Of no profit will be my counsel to you, much as I desire to give you (good) counsel, if it be that Allah willeth to leave you astray: He is your Lord! and to Him will ye return!"
