The Romans
وَإِذَآ أَذَقْنَا ٱلنَّاسَ رَحْمَةً فَرِحُوا۟ بِهَا ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌۢ بِمَا قَدَّمَتْ أَيْدِيهِمْ إِذَا هُمْ يَقْنَطُونَ
And when We let the people taste mercy, they rejoice therein, but if evil afflicts them for what their hands have put forth, immediately they despair.
Nearby ayahs help place verse 30:36 in sequence and meaning.
لِيَكْفُرُوا۟ بِمَآ ءَاتَيْنَـٰهُمْ ۚ فَتَمَتَّعُوا۟ فَسَوْفَ تَعْلَمُونَ
So that they will deny what We have granted them. Then enjoy yourselves, for you are going to know.
أَمْ أَنزَلْنَا عَلَيْهِمْ سُلْطَـٰنًا فَهُوَ يَتَكَلَّمُ بِمَا كَانُوا۟ بِهِۦ يُشْرِكُونَ
Or have We sent down to them an authority, and it speaks of what they were associating with Him?
أَوَلَمْ يَرَوْا۟ أَنَّ ٱللَّهَ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ وَيَقْدِرُ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يُؤْمِنُونَ
Do they not see that Allah extends provision for whom He wills and restricts [it]? Indeed, in that are signs for a people who believe.
فَـَٔاتِ ذَا ٱلْقُرْبَىٰ حَقَّهُۥ وَٱلْمِسْكِينَ وَٱبْنَ ٱلسَّبِيلِ ۚ ذَٰلِكَ خَيْرٌ لِّلَّذِينَ يُرِيدُونَ وَجْهَ ٱللَّهِ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
So give the relative his right, as well as the needy and the traveler. That is best for those who desire the countenance of Allah, and it is they who will be the successful.
