لِكُلِّ أُمَّةٍ جَعَلْنَا مَنسَكًا هُمْ نَاسِكُوهُ فَلَا يُنَازِعُنَّكَ فِي الْأَمْرِ وَادْعُ إِلَى رَبِّكَ إِنَّكَ لَعَلَى هُدًى مُّسْتَقِيمٍ
﴿٦٧﴾
سورة الحج
(22/67) For every nation we appointed a Law (single Sharia). They (should) follow (that Sharia). Therefore they should not dispute with you about My command. You invite to your Lord. Most surely you are indeed directed (towards Allah) upon Hidayet.
Surah Al-Hajj
