Reallocating the sanctity of ˹these˺ months1 is an increase in disbelief, by which the disbelievers are led ˹far˺ astray. They adjust the sanctity one year and uphold it in another, only to maintain the number of months sanctified by Allah, violating the very months Allah has made sacred. Their evil deeds have been made appealing to them. And Allah does not guide the disbelieving people.
Dr. Mustafa Khattab, the Clear Quran
