Jonah
قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًا ۗ سُبْحَـٰنَهُۥ ۖ هُوَ ٱلْغَنِىُّ ۖ لَهُۥ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۚ إِنْ عِندَكُم مِّن سُلْطَـٰنٍۭ بِهَـٰذَآ ۚ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ
They have said, "Allah has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority for this [claim]. Do you say about Allah that which you do not know?
Nearby ayahs help place verse 10:68 in sequence and meaning.
أَلَآ إِنَّ لِلَّهِ مَن فِى ٱلسَّمَـٰوَٰتِ وَمَن فِى ٱلْأَرْضِ ۗ وَمَا يَتَّبِعُ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّهِ شُرَكَآءَ ۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ
Unquestionably, to Allah belongs whoever is in the heavens and whoever is on the earth. And those who invoke other than Allah do not [actually] follow [His] "partners." They follow not except assumption, and they are not but falsifying
هُوَ ٱلَّذِى جَعَلَ لَكُمُ ٱلَّيْلَ لِتَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَسْمَعُونَ
It is He who made for you the night to rest therein and the day, giving sight. Indeed in that are signs for a people who listen.
قُلْ إِنَّ ٱلَّذِينَ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ لَا يُفْلِحُونَ
Say, "Indeed, those who invent falsehood about Allah will not succeed."
مَتَـٰعٌ فِى ٱلدُّنْيَا ثُمَّ إِلَيْنَا مَرْجِعُهُمْ ثُمَّ نُذِيقُهُمُ ٱلْعَذَابَ ٱلشَّدِيدَ بِمَا كَانُوا۟ يَكْفُرُونَ
[For them is brief] enjoyment in this world; then to Us is their return; then We will make them taste the severe punishment because they used to disbelieve
