Sincere worship

وَلَا تَطْرُدِ ٱلَّذِينَ يَدْعُونَ رَبَّهُم بِٱلْغَدَوٰةِ وَٱلْعَشِىِّ يُرِيدُونَ وَجْهَهُۥ ۖ مَا عَلَيْكَ مِنْ حِسَابِهِم مِّن شَىْءٍ وَمَا مِنْ حِسَابِكَ عَلَيْهِم مِّن شَىْءٍ فَتَطْرُدَهُمْ فَتَكُونَ مِنَ ٱلظَّـٰلِمِينَ

And do not send away those who call upon their Lord morning and afternoon, seeking His face [i.e., favor]. Not upon you is anything of their account and not upon them is anything of your account. So were you to send them away, you would [then] be of the wrongdoers.

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] -

وَأَنَّهُۥ لَمَّا قَامَ عَبْدُ ٱللَّهِ يَدْعُوهُ كَادُوا۟ يَكُونُونَ عَلَيْهِ لِبَدًا

And that when the Servant [i.e., Prophet] of Allāh stood up supplicating Him, they almost became about him a compacted mass."
