Is it permissible to perform the absentee funeral prayer (Salat al-Gha'ib) for those who have died from the coronavirus, in cases where it is difficult to pray over them, or only a small number of relatives have prayed over them?

The funeral prayer for the absent is obligatory for whoever died and was not prayed over. As for one who was prayed over, even by a small number, the funeral prayer for the absent is not obligatory for him. Scholars differed on its permissibility, and some verifying scholars concluded that it is not permissible.
