He prayed God to forgive the soul of the deceased and reward his great and noble deeds with paradise.
The deceased is survived by a number of children, including Ibrahim, a chief administrative officer in state house, Abuja,
In February, 2018, Buhari lost Halima Dauda, his niece and mother of Mohammed Sabi’u Tunde, his personal assistant.
She was the younger sister of Mamman Daura, a nephew of the president.
