يَـٰٓأَيُّهَا ٱلنَّاسُ ٱعْبُدُوا۟ رَبَّكُمُ ٱلَّذِى خَلَقَكُمْ وَٱلَّذِينَ مِن قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ

O mankind, worship your Lord, who created you and those before you, that you may become righteous -

Al-Baqarah 21

وَوَصَّىٰ بِهَآ إِبْرَٰهِـۧمُ بَنِيهِ وَيَعْقُوبُ يَـٰبَنِىَّ إِنَّ ٱللَّهَ ٱصْطَفَىٰ لَكُمُ ٱلدِّينَ فَلَا تَمُوتُنَّ إِلَّا وَأَنتُم مُّسْلِمُونَ

And Abraham instructed his sons [to do the same] and [so did] Jacob, [saying], "O my sons, indeed Allāh has chosen for you this religion, so do not die except while you are Muslims."

Al-Baqarah 132

صِبْغَةَ ٱللَّهِ ۖ وَمَنْ أَحْسَنُ مِنَ ٱللَّهِ صِبْغَةً ۖ وَنَحْنُ لَهُۥ عَـٰبِدُونَ

[And say, "Ours is] the religion of Allāh. And who is better than Allāh in [ordaining] religion? And we are worshippers of Him."

Al-Baqarah 138

قُلْ أَمَرَ رَبِّى بِٱلْقِسْطِ ۖ وَأَقِيمُوا۟ وُجُوهَكُمْ عِندَ كُلِّ مَسْجِدٍ وَٱدْعُوهُ مُخْلِصِينَ لَهُ ٱلدِّينَ ۚ كَمَا بَدَأَكُمْ تَعُودُونَ

Say, [O Muḥammad], "My Lord has ordered justice and that you direct yourselves [to the Qiblah] at every place [or time] of prostration, and invoke Him, sincere to Him in religion." Just as He originated you, you will return [to life] -

Al-A'raf 29

إِنَّمَا يَعْمُرُ مَسَـٰجِدَ ٱللَّهِ مَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمْ يَخْشَ إِلَّا ٱللَّهَ ۖ فَعَسَىٰٓ أُو۟لَـٰٓئِكَ أَن يَكُونُوا۟ مِنَ ٱلْمُهْتَدِينَ

The mosques of Allāh are only to be maintained by those who believe in Allāh and the Last Day and establish prayer and give zakāh and do not fear except Allāh, for it is expected that those will be of the [rightly] guided.

At-Tawbah 18
