9:100
وَٱلسَّـٰبِقُونَ ٱلْأَوَّلُونَ مِنَ ٱلْمُهَـٰجِرِينَ وَٱلْأَنصَارِ وَٱلَّذِينَ ٱتَّبَعُوهُم بِإِحْسَـٰنٍ رَّضِىَ ٱللَّهُ عَنْهُمْ وَرَضُوا۟ عَنْهُ وَأَعَدَّ لَهُمْ جَنَّـٰتٍ تَجْرِى تَحْتَهَا ٱلْأَنْهَـٰرُ خَـٰلِدِينَ فِيهَآ أَبَدًا ۚ ذَٰلِكَ ٱلْفَوْزُ ٱلْعَظِيمُ
And the first forerunners [in the faith] among the Muhajireen and the Ansar and those who followed them with good conduct - Allah is pleased with them and they are pleased with Him, and He has prepared for them gardens beneath which rivers flow, wherein they will abide forever. That is the great attainment.

وَمِنَ ٱلْأَعْرَابِ مَن يَتَّخِذُ مَا يُنفِقُ مَغْرَمًا وَيَتَرَبَّصُ بِكُمُ ٱلدَّوَآئِرَ ۚ عَلَيْهِمْ دَآئِرَةُ ٱلسَّوْءِ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ
And among the bedouins are some who consider what they spend as a loss and await for you turns of misfortune. Upon them will be a misfortune of evil. And Allah is Hearing and Knowing.
وَمِنَ ٱلْأَعْرَابِ مَن يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَـٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِ ۚ أَلَآ إِنَّهَا قُرْبَةٌ لَّهُمْ ۚ سَيُدْخِلُهُمُ ٱللَّهُ فِى رَحْمَتِهِۦٓ ۗ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
But among the bedouins are some who believe in Allah and the Last Day and consider what they spend as means of nearness to Allah and of [obtaining] invocations of the Messenger. Unquestionably, it is a means of nearness for them. Allah will admit them to His mercy. Indeed, Allah is Forgiving and Merciful.
وَمِمَّنْ حَوْلَكُم مِّنَ ٱلْأَعْرَابِ مُنَـٰفِقُونَ ۖ وَمِنْ أَهْلِ ٱلْمَدِينَةِ ۖ مَرَدُوا۟ عَلَى ٱلنِّفَاقِ لَا تَعْلَمُهُمْ ۖ نَحْنُ نَعْلَمُهُمْ ۚ سَنُعَذِّبُهُم مَّرَّتَيْنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٍ
And among those around you of the bedouins are hypocrites, and [also] from the people of Madinah. They have become accustomed to hypocrisy. You, [O Muhammad], do not know them, [but] We know them. We will punish them twice [in this world]; then they will be returned to a great punishment.
وَءَاخَرُونَ ٱعْتَرَفُوا۟ بِذُنُوبِهِمْ خَلَطُوا۟ عَمَلًا صَـٰلِحًا وَءَاخَرَ سَيِّئًا عَسَى ٱللَّهُ أَن يَتُوبَ عَلَيْهِمْ ۚ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
And [there are] others who have acknowledged their sins. They had mixed a righteous deed with another that was bad. Perhaps Allah will turn to them in forgiveness. Indeed, Allah is Forgiving and Merciful.
