الحج — Al-Hajj Ayat 67
لِكُلِّ اُمَّةٍ جَعَلْنَا مَنْسَكًا هُمْ نَاسِكُوْهُ فَلَا يُنَازِعُنَّكَ فِى الْاَمْرِ وَادْعُ اِلٰى رَبِّكَۗ اِنَّكَ لَعَلٰى هُدًى مُّسْتَقِيْمٍ
Likulli ummatin ja‘alnā mansakan hum nāsikūhu falā yunāzi‘unnaka fil-amri wad‘u ilā rabbik(a), innaka la‘alā hudam mustaqīm(in).
"For every religion We have appointed rites which they perform. So, [O Muhammad], let the disbelievers not contend with you over the matter but invite them to your Lord. Indeed, you are upon straight guidance."
