The gristle spells out the word "Allah" in Arabic
Diners have been flocking to a restaurant in northern Nigeria to see pieces of meat which the owner says are inscribed with the name of Allah.
What looks like the Arabic word for God and the name of the prophet Muhammad were discovered in pieces of beef by a diner in Birnin Kebbi.
He was about to eat it, when he suddenly noticed the words in the gristle, the restaurant owner said.
A search of the kitchen's meat revealed three more pieces which bore the names.
The meat was boiled and then fried before being served, owner Kabiru Haliru told newspaper Weekly Trust.
"When the writings were discovered there were some Islamic scholars who come and eat here and they all commented that it was a sign to show that Islam is the only true religion for mankind," he said.
The restaurant has kept the pieces of meat for visitors to see.
Thousands of people have already gone to the restaurant to see them since they were discovered last week.
A vet told the newspaper the words "defied scientific explanation".
"Supposing only one piece of meat was found then it would be suspicious, but given the circumstances there is no explanation," Dr Yakubu Dominic said.
