Surah Al-Hijr, verse 89

وَلَقَدْ ءَاتَيْنَـٰكَ سَبْعًۭا مِّنَ ٱلْمَثَانِى وَٱلْقُرْءَانَ ٱلْعَظِيمَ ﴿٨٧﴾

And We have certainly given you, [O Muḥammad], seven of the often repeated [verses] and the great Qur’ān.

لَا تَمُدَّنَّ عَيْنَيْكَ إِلَىٰ مَا مَتَّعْنَا بِهِۦٓ أَزْوَٰجًۭا مِّنْهُمْ وَلَا تَحْزَنْ عَلَيْهِمْ وَٱخْفِضْ جَنَاحَكَ لِلْمُؤْمِنِينَ ﴿٨٨﴾

Do not extend your eyes toward that by which We have given enjoyment to [certain] categories of them [i.e., the disbelievers], and do not grieve over them. And lower your wing [i.e., show kindness] to the believers.

كَمَآ أَنزَلْنَا عَلَى ٱلْمُقْتَسِمِينَ ﴿٩٠﴾

Just as We had revealed [scriptures] to the separators

ٱلَّذِينَ جَعَلُوا۟ ٱلْقُرْءَانَ عِضِينَ ﴿٩١﴾

Who have made the Qur’ān into portions.
