وَظَلَّلْنَا عَلَيْكُمُ الْغَمَامَ وَأَنزَلْنَا عَلَيْكُمُ الْمَنَّ وَالسَّلْوَىٰ ۖ كُلُوا مِن طَيِّبَاتِ مَا رَزَقْنَاكُمْ ۖ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوا أَنفُسَهُمْ يَظْلِمُونَ
Wa zallanaa 'alaykumul gamaama wa anzalnaa 'alaykumul manna was salwaa kuloo min tayyibaati maa razaqnaakum wa maa zalamoonaa wa laakin kaanoo anfusahum yazlimoon
And we shaded you with clouds and sent down to you manna and quails: "Eat from the good things we have provided for you." They did not wrong us, but they were wronging themselves.
The grammar turns in the middle of this verse. It begins in the second person, addressing the audience directly as the shade and the food are described, and then shifts to the third person for the closing judgement, so the rebuke arrives as if spoken about someone rather than to them. Arabic rhetoric names this turn iltifāt and treats it as deliberate, not as a slip.
