Luqmān

وَمَن كَفَرَ فَلاَ يَحْزُنكَ كُفْرُهُ إِلَيْنَا مَرْجِعُهُمْ فَنُنَبّـِئُهُم بِمَا عَمِلُوا إِنَّ اللَّهَ عَلِيمٌ بِذَاتِ الصُّدُورِ

نُمَتّـِعُهُمْ قَلِيلاً ثُمَّ نَضْطَرُّهُمْ إِلَي عَذَابٍ غَلِيظٍ

23. “And whoever disbelieves, let not his disbelief grieve you, unto Us is their return then will We inform them of what they did. Verily Allah is the knower of what is in the hearts.”
24. “We give them to enjoy a little, then will We drive them to a severe chastisement.”

The holy Prophet of Islam (S) was sympathetic for all humankind and he even did toil for the deviation and disbelief of the opponents, too. So, Allah says:

For, you have performed your duty very well, and it is the disbeliever who has been unjust to himself. These kinds of meanings, which have been frequently mentioned in the Qur’an, show that the holy Prophet of Islam (S) severely toiled when he observed that an ignorant and obstinate group of people left the way of Allah and went astray after having a lot of clear evidences and manifest signs; he became so sad and grieved that Allah consoled him many times. And such kind is the way and manner of a sympathetic leader.

And also he should not be worried that a group of people enjoy the comforts of life in this world and are not involved in punishment though they disbelieve and are unjust and cruel, because it is not so late and they all will return to Allah and He will inform them of both their deeds and the bitter and evil fruits of their deeds. The verse says:

Allah, the knowing, is aware of not only their deeds but also of the secrets and hidden intentions in their hearts. The verse continues saying:

This meaning that on the Day of Hereafter Allah will inform people of their deeds or that He will inform them of what they differed in, has been revealed through a great deal of verses of the Holy Qur’an. The Qur’anic term /nunabbi’ukum/ is derived from /naba’/ which, according to what Raqib has cited in Mufradat, is used for a news that has an important content and benefit, and it is also explicit, manifest, and free from any falsehood. This makes it clear that these meanings, point to the fact that on the Hereafter Day Allah will divulge the people’s deeds in a manner that there will remain no place of objection and denial for anyone.

He will make appear entirely whatever people do in this world and they often forget them in this world, and He will make them ready for reckoning and recompense. Even that which passes in the mind of a person and none is aware of, will completely be reported to their owners. Then in the next verse, He implies that their enjoyment of the life of this world should not make the Prophet (S) surprise, because He gives them a little share of the provision of the world, and whatever this provision may be, it is scanty, and finally they will compulsorily be driven into a just severe punishment, a punishment which is constant and painful.

The verse says:

This meaning may point to the fact that they should not think that they are out of the grasp of Allah’s power. He Himself desires to let them be free to be tried, the argument be completed to them, and other aims; and this little provision given to them is from His side, too. And how different is the circumstance of this group who are compulsorily and scornfully driven to the divine severe chastisement from that of those who submit their whole entity to Allah and have taken hold the firm rope of Allah. They live in this world piously and righteously, and then, in Hereafter, they will enjoy the bounties of Allah with His mercy.
