—namely, because they were keenly aware of his ﷺ stern warning in this regard, his emphatic denunciation, and his curse upon anyone who did so; thus the intent is the prohibition of praying at graves.
• His words, “Every spot that is deliberately singled out for prayer has thereby been taken as a mosque,” mean that it has been designated for prayer even if no structure is built there.
• His words, “Rather, every place in which prayer is performed is called a mosque,” mean that even when the place was not intentionally set aside for that purpose—but prayer happened to be offered there incidentally when its time came—it still bears the name “mosque.”
• His words, “as the Prophet ﷺ said: ‘The whole earth has been made for me a place of worship and a means of purification,’” are cited as proof for the previous statement, for in this ḥadīth the Prophet ﷺ called the earth a mosque, indicating that prayer is lawful in every part of it except where other evidence has ruled otherwise.
