104وَلْتَكُن مِّنكُمْ أُمَّةٌ يَدْعُونَ إِلَى ٱلْخَيْرِ وَيَأْمُرُونَ بِٱلْمَعْرُوفِ وَيَنْهَوْنَ عَنِ ٱلْمُنكَرِ ۚ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
105وَلَا تَكُونُوا۟ كَٱلَّذِينَ تَفَرَّقُوا۟ وَٱخْتَلَفُوا۟ مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْبَيِّنَـٰتُ ۚ وَأُو۟لَـٰٓئِكَ لَهُمْ عَذَابٌ عَظِيمٌ
106يَوْمَ تَبْيَضُّ وُجُوهٌ وَتَسْوَدُّ وُجُوهٌ ۚ فَأَمَّا ٱلَّذِينَ ٱسْوَدَّتْ وُجُوهُهُمْ أَكَفَرْتُم بَعْدَ إِيمَـٰنِكُمْ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ
107وَأَمَّا ٱلَّذِينَ ٱبْيَضَّتْ وُجُوهُهُمْ فَفِى رَحْمَةِ ٱللَّهِ هُمْ فِيهَا خَـٰلِدُونَ
108تِلْكَ ءَايَـٰتُ ٱللَّهِ نَتْلُوهَا عَلَيْكَ بِٱلْحَقِّ ۗ وَمَا ٱللَّهُ يُرِيدُ ظُلْمًا لِّلْعَـٰلَمِينَ
109وَلِلَّهِ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۚ وَإِلَى ٱللَّهِ تُرْجَعُ ٱلْأُمُورُ
[104-109] There should always be among you some people who invite to what is good and enjoin what is right and forbid what is wrong: They alone will attain true success. And do not be like those, who became divided into sects and got involved in differences of opinion even after receiving clear teachings.86 Those (who have caused divisions), shall suffer a terrible punishment on the Day, when the faces (of some) will be brightened with joy and those of others shall be blackened with gloom. (It will be said to those,) whose faces shall be blackened, "Did you adopt the way of disbelief after receiving Faith? Well, then taste the torment for showing gross ingratitude towards it." As regards those, whose faces will be brightened, they will enjoy Allah's mercy and abide therein for ever. These are Allah's Revelations, which We are reciting to you in all Truth, for Allah does not will to be unjust87 to the people of the world. All that is in the heavens and the earth belongs to Allah, and to Allah are all the matters presented.
86This refers to those communities which received the Guidance and clear teachings from the Messengers of Allah but after some time discarded the basic principles of the Guidance and divided themselves into different sects on the basis of irrelevant and minor side-issues and were involved in useless and meaningless squabbles. They became so engrossed in these things that they totally forgot the mission which Allah had entrusted to them and lost interest even in the basic principles on which, in fact, depends the real success of humanity.
87As Allah, does not will to be unjust to the people of the world, He is showing them Guidance and warning them before-hand of those things of which they shall have ultimately to render an account. Thus, those who follow the crooked ways even after this and do not return to the Right Way are doing injustice to themselves
