كَانَ ٱلنَّاسُ أُمَّةٗ وَٰحِدَةٗ فَبَعَثَ ٱللَّهُ ٱلنَّبِيِّـۧنَ مُبَشِّرِينَ وَمُنذِرِينَ وَأَنزَلَ مَعَهُمُ ٱلۡكِتَٰبَ بِٱلۡحَقِّ لِيَحۡكُمَ بَيۡنَ ٱلنَّاسِ فِيمَا ٱخۡتَلَفُواْ فِيهِۚ وَمَا ٱخۡتَلَفَ فِيهِ إِلَّا ٱلَّذِينَ أُوتُوهُ مِنۢ بَعۡدِ مَا جَآءَتۡهُمُ ٱلۡبَيِّنَٰتُ بَغۡيَۢا بَيۡنَهُمۡۖ فَهَدَى ٱللَّهُ ٱلَّذِينَ ءَامَنُواْ لِمَا ٱخۡتَلَفُواْ فِيهِ مِنَ ٱلۡحَقِّ بِإِذۡنِهِۦۗ وَٱللَّهُ يَهۡدِي مَن يَشَآءُ إِلَىٰ صِرَٰطٖ مُّسۡتَقِيمٍ
All men used to be a single ’Ummah (i.e. on a single faith). Then (after they differed in matters of faith), Allah sent prophets carrying good news and warning, and sent down with them the Book with Truth to judge between people in matters of their dispute. But it was no other than those to whom it (the Book) was given who, led by envy against each other, disputed it after the clear signs had come to them. Then Allah, by His will, guided those who believed to the truth over which they disputed; and Allah guides whom He wills to the straight path.
أَمۡ حَسِبۡتُمۡ أَن تَدۡخُلُواْ ٱلۡجَنَّةَ وَلَمَّا يَأۡتِكُم مَّثَلُ ٱلَّذِينَ خَلَوۡاْ مِن قَبۡلِكُمۖ مَّسَّتۡهُمُ ٱلۡبَأۡسَآءُ وَٱلضَّرَّآءُ وَزُلۡزِلُواْ حَتَّىٰ يَقُولَ ٱلرَّسُولُ وَٱلَّذِينَ ءَامَنُواْ مَعَهُۥ مَتَىٰ نَصۡرُ ٱللَّهِۗ أَلَآ إِنَّ نَصۡرَ ٱللَّهِ قَرِيبٞ
Do you think that you will enter Paradise while you have not yet been visited by (difficult) circumstances like those that were faced by the people who passed away before you? They were afflicted by hardship and suffering, and were so shaken down that the prophet, and those who believed with him, started saying: “When (will come) the help of Allah?” (Then, they were comforted by the Prophet who said to them) ‘Behold, the help of Allah is near.’
