Al-An'am 6:52
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
Wala tatrudi allatheenayadAAoona rabbahum bilghadati walAAashiyyiyureedoona wajhahu ma AAalayka min hisabihimmin shay-in wama min hisabika AAalayhim minshay-in fatatrudahum fatakoona mina aththalimeen
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.
Do not expel those who call out to their Lord morning and evening seeking His pleasure. You are not responsible for anything in their account, and they are not responsible for anything in your account, that you should expel them, and thus become one of the unjust.
