What is the meaning of the Almighty's saying: "And what has been dedicated to other than Allah" in verse 173 of Surat Al-Baqarah, and does this include forbidding the eating of food offered in India after reciting Al-Fatiha in the name of some righteous individuals?

Ibn Kathir (may Allah have mercy on him) views the verse in question from Surat Al-Baqarah as meaning that any animal slaughtered in the name of other than Allah, such as those slaughtered for idols, rivals, or divining arrows, is forbidden. In his interpretation of verse 3 from Surat Al-Ma'idah, he clarified that anything slaughtered with a name other than Allah’s mentioned over it is unanimously forbidden, because Allah has enjoined slaughtering in His magnificent Name. As for "and that which has been slaughtered on stone altars (An-Nusub)," these "Nusub" were stones around the Kaaba where the people of Jahiliyyah used to slaughter. Allah forbade the consumption of these slaughtered animals and deemed them unlawful, even if Allah's name was mentioned over them at the altars, because it is considered an act of polytheism.

Therefore, any animal slaughtered with a name other than Allah's mentioned over it, whether it be a prophet, a saint, an idol, a devil, or anything else, is impermissible to consume.
