لَٰكِنِ ٱلرَّسُولُ وَٱلَّذِينَ ءَامَنُوا۟ مَعَهُۥ جَٰهَدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ
Lākini'l-rasūlu wa'lladhīna āmanū maʿahū jāhadū bi-amwālihim wa anfusihim; wa ulāʾika lahumu'l-khayrāt; wa ulāʾika humu'l-mufliḥūn · Aʿadda'llāhu lahum jannātin tajrī min taḥtiha'l-anhāru khālidīna fīhā; dhālika'l-fawzu'l-ʿaẓīm
"But the Messenger and those who believed with him strove with their wealth and their lives. All good things are theirs; it is they who prosper. · God has prepared for them gardens with rivers running beneath them, abiding in them. That is the great attainment."
The particle of correction (istidrāk): "but." The verse is set directly opposite the preceding block.
I record this as an observation about the structure: the sūra closes each block of negative description with a counter-description. The same structure was present at 67-71 (the hypocrites / the believers). The same thing is repeated here at 86-88. This is a weave verifiable within the sūra.
And lahumu'l-khayrāt must be recorded: khayrāt — the plural of khayr; not one determinate thing but the whole of good things.
