Surah Al-Hajj (The Pilgrimage), Verse 67

لِكُلِّ اُمَّةٍ جَعَلْنَا مَنْسَكًا هُمْ نَاسِكُوْهُ فَلَا یُنَازِعُنَّكَ فِی الْاَمْرِ وَادْعُ اِلٰی رَبِّكَ اِنَّكَ لَعَلٰی هُدًی مُّسْتَقِیْمٍ ۟

Likulli ummatin ja'alnaa mansakan hum naasikoohu falaa yunaazi 'unnaka fil amr; wad'u ilaa Rabbika innaka la 'alaa hudan mustaqeem

“To every People have We appointed rites and ceremonies which they must follow: let them not then dispute with thee on the matter, but do thou invite (them) to thy Lord: for thou art assuredly on the Right Way.”

Quran 22:67 (Yusuf Ali Translation)
