Read bismillah before slaughter

إِنَّمَا حَرَّمَ عَلَيْكُمُ ٱلْمَيْتَةَ وَٱلدَّمَ وَلَحْمَ ٱلْخِنزِيرِ وَمَآ أُهِلَّ لِغَيْرِ ٱللَّهِ بِهِۦ ۖ فَمَنِ ٱضْطُرَّ غَيْرَ بَاغٍۢ وَلَا عَادٍۢ فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ

He has only forbidden you dead meat, and blood, and the flesh of swine, and any (food) over which the name of other than Allah has been invoked. But if one is forced by necessity, without wilful disobedience, nor transgressing due limits,- then Allah is Oft-Forgiving, Most Merciful.

وَلِكُلِّ أُمَّةٍۢ جَعَلْنَا مَنسَكًۭا لِّيَذْكُرُوا۟ ٱسْمَ ٱللَّهِ عَلَىٰ مَا رَزَقَهُم مِّنۢ بَهِيمَةِ ٱلْأَنْعَٰمِ ۗ فَإِلَٰهُكُمْ إِلَٰهٌۭ وَٰحِدٌۭ فَلَهُۥٓ أَسْلِمُوا۟ ۗ وَبَشِّرِ ٱلْمُخْبِتِينَ

To every people did We appoint rites (of sacrifice), that they might celebrate the name of Allah over the sustenance He gave them from animals (fit for food). But your god is One God: submit then your wills to Him (in Islam): and give thou the good news to those who humble themselves,-

وَٱلْبُدْنَ جَعَلْنَٰهَا لَكُم مِّن شَعَٰٓئِرِ ٱللَّهِ لَكُمْ فِيهَا خَيْرٌۭ ۖ فَٱذْكُرُوا۟ ٱسْمَ ٱللَّهِ عَلَيْهَا صَوَآفَّ ۖ فَإِذَا وَجَبَتْ جُنُوبُهَا فَكُلُوا۟ مِنْهَا وَأَطْعِمُوا۟ ٱلْقَانِعَ وَٱلْمُعْتَرَّ ۚ كَذَٰلِكَ سَخَّرْنَٰهَا لَكُمْ لَعَلَّكُمْ تَشْكُرُونَ

The sacrificial camels we have made for you as among the symbols from Allah: in them is (much) good for you: then pronounce the name of Allah over them as they line up (for sacrifice): when they are down on their sides (after slaughter), eat ye thereof, and feed such as (beg not but) live in contentment, and such as beg with due humility: thus have We made animals subject to you, that ye may be grateful.
