The Command to convey the Message of Tawhid
Here Allah commands His Messenger to convey the Message and recite the Qur'an to people. He tells him that he will be brought back to the return, which is the Day of Resurrection, where he will be asked about the Prophethood he was entrusted with.
So Allah says;
إِنَّ الَّذِي فَرَضَ عَلَيْكَ الْقُرْانَ لَرَادُّكَ إِلَى مَعَادٍ
Verily, He Who has given you the Qur'an, will surely bring you back to the return.
meaning, `the One Who has commanded you to put it into practice among mankind,'
لَرَادُّكَ إِلَى مَعَادٍ
will surely bring you back to the return.
`On the Day of Resurrection, where He will question you concerning that,' as Allah said;
فَلَنَسْـَلَنَّ الَّذِينَ أُرْسِلَ إِلَيْهِمْ وَلَنَسْـَلَنَّ الْمُرْسَلِينَ
Then surely, We shall question those to whom it was sent and verily, We shall question the Messengers. (7;6)
Allah said;
يَوْمَ يَجْمَعُ اللَّهُ الرُّسُلَ فَيَقُولُ مَاذَا أُجِبْتُمْ
On the Day when Allah will gather the Messengers together and say to them;"What was the response you received!" (5;109)
And He said;
وَجِـىءَ بِالنَّبِيِّيْنَ وَالشُّهَدَاءِ
and the Prophets and the witnesses will be brought forward. (39;69)
In his Tafsir of his Sahih, Al-Bukhari recorded that Ibn Abbas commented on the Ayah;
لَرَادُّكَ إِلَى مَعَادٍ
(will surely bring you back to the return).
"To Makkah."
This was also recorded by An-Nasa'i in his Tafsir in his Sunan, and by Ibn Jarir.
Al-`Awfi also reported from Ibn `Abbas that the phrase;
لَرَادُّكَ إِلَى مَعَادٍ
(will surely bring you back to the return),
means, "will surely bring you back to Makkah as He brought you out of it."
Muhammad bin Ishaq recorded that Mujahid commented on;
لَرَادُّكَ إِلَى مَعَادٍ
(will surely bring you back to the return). He said,
"Back to your place of birth in Makkah."
Ibn Abbas is also reported to have interpreted it variously referring to death, to the Day of Resurrection which will come after death, and to Paradise which will be his reward and his destiny for putting the Message of Allah into practice and conveying it to the humans and Jinns, and because he is the most perfect, most eloquent and most noble of all the creation of Allah.
Allah's saying;
قُل رَّبِّي أَعْلَمُ مَن جَاء بِالْهُدَى وَمَنْ هُوَ فِي ضَلَلٍ مُّبِينٍ
Say;"My Lord is Aware of him who brings guidance, and of him who is in manifest error."
means;"Say, O Muhammad, to those among your people who oppose you and disbelieve you, among the idolators and those who follow them in their disbelief, `My Lord knows best which of us, you or I, is rightly guided, and you will come to know for which of us will be the (happy) end in the Hereafter, and for which of us will be a good end and victory in this world and in the Hereafter'."
Then Allah reminds His Prophet the numerous blessings He granted to him and mankind by virtue of sending him to them
