Chapter: Reports Concerning Sacrificing to Other than Allah

Allah the Exalted says: “Say, ‘Indeed my prayer, my sacrifice, my living and my dying are for Allah, Lord of all worlds; He has no partner. With this I have been commanded, and I am the first of the Muslims.’ ” (Al-Anʿām 162-163)

Connection of the chapter to the Book of Tawḥīd: it sets forth a category of idolatry that contradicts pure monotheism.

“What has been reported concerning sacrificing to other than Allah”: that is, the warnings issued about it and the legal ruling it carries.

Nusukī: my sacrifice.
Maḥyāya: what I do during my life.
Mamātī: the state of faith and righteous deeds upon which I die.
“With that I have been commanded”: my Lord has instructed me to be utterly sincere in worship.
“The first of the Muslims”: the first to comply from this nation.

Overall meaning of the verse: Allah commands His Prophet to declare to the idolaters—those who worship other than Allah and slaughter for others—that he devotes exclusively to Allah his prayer, his sacrifice, and all that he does in life and at death, directing every act to Him alone without associating anyone with Him, in stark contrast to their polytheism.

Relevance of the verse to the chapter: it shows that offering a sacrifice to anyone besides Allah is an act of shirk.
