Qur'an 22:28

لِّيَشْهَدُوا۟ مَنَـٰفِعَ لَهُمْ وَيَذْكُرُوا۟ ٱسْمَ ٱللَّهِ فِىٓ أَيَّامٍ مَّعْلُومَـٰتٍ عَلَىٰ مَا رَزَقَهُم مِّنۢ بَهِيمَةِ ٱلْأَنْعَـٰمِ ۖ فَكُلُوا۟ مِنْهَا وَأَطْعِمُوا۟ ٱلْبَآئِسَ ٱلْفَقِيرَ

That they may witness things that are of benefit to them, and mention the name of Allah on appointed days over the beast of cattle that He hath bestowed upon them. Then eat thereof and feed therewith the poor unfortunate.
