Will Buhari’s death bring solution to Nigeria’s problems?

The rate at which our people are moving from mountain to campgrounds in prayer; wishing their President Muhammadu Buhari urgent death is very shocking and disappointing. Truly, the president is very sick and he's receiving treatments abroad. But, the question that has been troubling my mind is that, when one's relative is not feeling too well, do we pray he dies, irrespective of any reason whatsoever?
