(Al-Hajj) 22 : 34
وَلِكُلِّ أُمَّةٍ جَعَلْنَا مَنْسَكًا لِيَذْكُرُوا اسْمَ اللَّهِ عَلَىٰ مَا رَزَقَهُمْ مِنْ بَهِيمَةِ الْأَنْعَامِ ۗ فَإِلَٰهُكُمْ إِلَٰهٌ وَاحِدٌ فَلَهُ أَسْلِمُوا ۗ وَبَشِّرِ الْمُخْبِتِينَ

And for every community, We have appointed a sacrifice, so that they may remember the name of Lord Allah upon what He has provided for them of animals. Then your Deity is the Single Deity, so you submit wholly to Him; and you inform the Herald to those who submit all their thoughts, speeches, and deeds to Lord.
