Muslims perform salatul-Kusuf
in times of drought
during an eclipse
Before burying their corpse
when on a journey
Correct answer is B
Muslims perform Salatul-kusuf during an eclipse. Salat ul-Kusuf is a prayer offered during a lsolar eclipse; Salat ul-Khusuf is performed during a lunar eclipse. They are both Nafl (non-obligatory) with two rakat prayers that shoud be performed by the Muslim community in congregation.
