Clarification of the stronger position regarding the ruling on praying in a cemetery and in usurped land?

The Shaykh : And this is the correct view: that the prayer is not valid in a cemetery. It is not like usurped land. The stronger view regarding usurped land is that the prayer is valid in it. However, the prayer is not valid in a cemetery. The difference is apparent, because the prohibition of praying in usurped land is due to the right of another person, not because it is a means to shirk (associating partners with Allah). As for praying in a cemetery, it is a means to shirk. And if the Prophet (peace and blessings be upon him) said: meaning: even if you were outside, how much more so for one who prays at the grave, makes it his qiblah (direction of prayer), and seeks blessing from its location? Yes.
