Here Allah tells us about His servant and Messenger Nuh, peace be upon him, who was the first Messenger sent by Allah to the people of earth after they started to worship idols. Allah sent him to forbid that and to warn people of the consequences of idol worship. But his people belied him and continued their evil practice of worshipping idols besides Allah. Allah revealed that their disbelieving in him was akin to disbelieving in all the Messengers, So Allah said:

[كَذَّبَتْ قَوْمُ نُوحٍ الْمُرْسَلِينَ - إِذْ قَالَ لَهُمْ أَخُوهُمْ نُوحٌ أَلاَ تَتَّقُونَ ]

(The people of Nuh belied the Messengers. When their brother Nuh said to them: "Will you not have Taqwa'') meaning, `do you not fear Allah when you worship others instead of Him'

[إِنِّي لَكُمْ رَسُولٌ أَمِينٌ ]

(I am a trustworthy Messenger to you.) means, `I am the Messenger of Allah to you, faithfully fulfilling the mission with which Allah has sent me. I convey the Messages of my Lord to you, and I do not add anything to them or take anything away from them.,

[فَاتَّقُواْ اللَّهَ وَأَطِيعُونِ وَمَآ أَسْـَلُكُمْ عَلَيْهِ مِنْ أَجْرٍ]

(So have Taqwa of Allah, and obey me. No reward do I ask of you for it;) means, `I do not want any payment for the advice I give you; I will save my reward for it with Allah. '

[فَاتَّقُواْ اللَّهَ وَأَطِيعُونِ ]

(So have Taqwa of Allah, and obey me.) `It is clear to you that I am telling the truth and that I am faithfully fulfilling the mission with which Allah has entrusted me.'

[قَالُواْ أَنُؤْمِنُ لَكَ وَاتَّبَعَكَ الاٌّرْذَلُونَ - قَالَ وَمَا عِلْمِى بِمَا كَانُواْ يَعْمَلُونَ - إِنْ حِسَابُهُمْ إِلاَّ عَلَى رَبِّى لَوْ تَشْعُرُونَ - وَمَآ أَنَاْ بِطَارِدِ الْمُؤْمِنِينَ - إِنْ أَنَا إِلاَّ نَذِيرٌ مُّبِينٌ ]

(111. They said: "Shall we believe in you, when the inferior follow you'') (112. He said: "And what knowledge have I of what they used to do'') (113. "Their account is only with my Lord, if you could (but) know.'') (114. "And I am not going to drive away the believers.'') (115. "I am only a plain warner.'')
