Surah Al-Hajj, ayah 28

لِّيَشۡهَدُواْ مَنَٰفِعَ لَهُمۡ وَيَذۡكُرُواْ ٱسۡمَ ٱللَّهِ فِيٓ أَيَّامٖ مَّعۡلُومَٰتٍ عَلَىٰ مَا رَزَقَهُم مِّنۢ بَهِيمَةِ ٱلۡأَنۡعَٰمِۖ فَكُلُواْ مِنۡهَا وَأَطۡعِمُواْ ٱلۡبَآئِسَ ٱلۡفَقِيرَ ٢٨

Lliyashhadū manāfi'a lahum wayadhkurusmallāhi fī ayyāmim ma'lūmātin 'alā mā razaqahum mim bahīmatil-an'āmi fakulū minhā wa at'imul-bā'isal-faqīr

That they may witness [i.e., attend] benefits for themselves and mention the name of Allāh on known [i.e., specific] days over what He has provided for them of [sacrificial] animals.⁹²⁴ So eat of them and feed the miserable and poor.
