Nigeria's most senior Muslim cleric has rejected a new gender equality bill, which proposes that women and men inherit an equal share.
The Sultan of Sokoto, Mohamed Sa'ad Abubakar, said Muslims would not accept the violation of Islamic law guaranteeing men a greater share.
Nigeria's main Christian body has welcomed the bill, saying its religion permitted equal inheritance.
Activists have pushed for the bill to end discrimination against women.

Nigeria is a deeply religious society with roughly the same number of Christians and Muslims.
Speaking at a Koranic recitation ceremony in northern Zamfara state, the sultan said: "Our religion is our total way of life. Therefore, we will not accept any move to change what Allah permitted us to do."
He added: "Islam is a peaceful religion; we have been living peacefully with Christians and followers of other religions in this country. Therefore, we should be allowed to perform our religion effectively."
