the Supreme Court in Lagos, Nigeria, confirmed the death sentence of Abdullahi Ada, who, eight years ago, played a prominent role in the killing of Alhaji Abdullahi Umaru of Randali village in Kebbi state, for allegedly insulting Holy Prophet Mohammed.
Abdullahi was murdered on July 14, 1999. Three others, identified as Shallah, Yaro and Abubakar, who also participated in death are also to die by hanging.
Ada went to the village head to explain their intention to murder the deceased for defaming the name of Holy Prophet Mohammed. Yaro informed the villagers that Abdullahi had insulted the Prophet Mohammed and incited the mob by reading from Risala that whoever insulted Prophet Mohammed must be killed.
Abubakar confessed to slitting Abdullahi's throat along Randali-Kardi Road near the Kardi burial ground after Yaro pronounced the death sentence on him. Justice George Oguntade, Sylvester Umaru Onu, Alome Mariam Mukhtar, Walter Samuel Nkanu Onnoghen and Ibrahim Tanko Muhammad presided.
