Surah Al A'raf Tafseer

فَلَنَسْأَلَنَّ الَّذِينَ أُرْسِلَ إِلَيْهِمْ

Then surely, We shall question those (people) to whom it (the Book) was sent,

is similar to the Ayat,

وَيَوْمَ يُنَـدِيهِمْ فَيَقُولُ مَاذَا أَجَبْتُمُ الْمُرْسَلِينَ

And (remember) the Day (Allah) will call them, and say:"What answer gave you to the Messengers!" (28:65)

and,

يَوْمَ يَجْمَعُ اللَّهُ الرُّسُلَ فَيَقُولُ مَاذَا أُجِبْتُمْ قَالُواْ لَا عِلْمَ لَنَأ إِنَّكَ أَنتَ عَلَّـمُ الْغُيُوبِ

On the Day when Allah will gather the Messengers together and say to them:"What was the response you received!"

They will say:"We have no knowledge, verily, only You are the Knower of all that is unseen." (5:109)

Allah will question the nations, on the Day of Resurrection, how they responded to His Messengers and the Messages He sent them with. He will also question the Messengers if they conveyed His Messages.

So, Ali bin Abi Talhah reported from Ibn Abbas, who said commenting on the Ayah:

(Then surely, We shall question those (people) to whom it (the Book) was sent and verily, We shall question the Messengers). He said;

"About what they conveyed."

فَلَنَقُصَّنَّ عَلَيْهِم بِعِلْمٍ وَمَا كُنَّا غَأيِبِينَ
