Some Ulama who were staunch upholders of the covid protocols died on a Friday.

Answer

No it does not mean that they were correct. Even if we see them sitting under the Arsh, it will not mean that they were correct in their haraam views acquired from the atheist enemies of Allah Ta‟ala. There is no certitude that every person who dies on a Friday night is forgiven or that he was on the path of righteousness. Millions of kuffaar and fussaaq all over the world die on Friday nights. Just as there is no certitude that every person who dies on the battlefield is a Shaheed although we shall say that he is a martyr so too does it apply to deviates who die on a Friday. Only Allah Ta‟ala knows.

The criterion for us is the Shariah, not the occasion of a person‟s death. There is no need to be perturbed. Allah Ta‟ala deals with people as He deems appropriate. We are not concerned with what Allah Ta‟ala will decide about the deceased. We are concerned with His Deen. Whoever, is astray in terms of the Shariah, shall be proclaimed as such. If Allah Ta‟ala forgives even the deviate, it is His Prerogative to do so. It is His Rahmat. He does as He wills.
