Prominent Nigerian preacher TB Joshua has predicted the death of a politician following the Nigerian presidential elections.

Joshua, who leads the Synagogue Church of All Nations, said during a service on Sunday that he was seeing the death of a politician due to "heated up" politics in the beleaguered country.

After being delayed for several weeks to allow military forces to secure Nigeria's northeastern states from terrorist group Boko Haram, the country's presidential elections were finally pushed ahead on Saturday. The election pitted former dictator Muhammadu Buhari, who is a Muslim, against incumbent president Goodluck Jonathan who is a Christian.

According to The Guardian, election results released on Tuesday showed that Buhari won the elections.

Joshua predicted the death of a "great man" immediately following the elections.

"(A) great man among the politicians will likely lose his life... I am seeing this kind of thing happening in the night," Joshua is quoted by Naij as telling his congregants on Sunday.

"Wednesday and Thursday of this coming week and next week, make sure you fast and pray," he urged members of All Nations.

Joshua made a similar prophecy last year when he spoke of a "dark cloud" hovering over Nigeria. The preacher interpreted the cloud as a sign of "lawlessness," whereby two political parties would declare themselves as winners in the then-upcoming elections.

Now, he told his ministry that God is beginning to remove the cloud.

According to Naij, TB Joshua also urged All Nations members to avoid violence and not allow themselves to be used for political intentions.

"There is a difference between your faith and politics. Do not play politics as if it is your faith. 'Do or die' is not politics. Politics is a game," he said.

Joshua is popular in Nigeria and abroad for his supposed prophetic and healing abilities. He attracted controversy last year when a six-storey building in his church compound collapsed and killed more than 100 people, most of them South African nationals. Government officials claimed that structural problems brought about the collapse.

The state government's investigation of the incident through the Coroner's Court is still ongoing.
