According to Serer tradition, the king was very ill before his death and ruled for 27 winters (27 years) before his successor - Maad a Sinig Mahecor Joof succeeded to the throne.

When the King died, there was a period of mourning and it took a little while to prepare for the Coronation ceremony of Maad a Sinig Mahecor Joof according to Serer custom and tradition.

Regarding the year Maad a Sinig Kumba Ndoffene Fa Ndeb Joof died, there is consensus that it was in 1923,[14] more specifically on 21 December 1923 at Diakhao.

These prefixes were later additions (during and after the reigne of Maad a Sinig Kumba Ndoffene Fa Ndeb) to differentiate the two Kings of Sine who shared the same name and surname.

The noble Council objected, and told him they had made their choice, and the people of Sine had appointed Maad Kumba Ndoffene Fa Ndeb as their king.

Lefilliâtre later retracted his statements and became the main supporter of Maad Kumba Ndoffene Fa Ndeb within the French administration of Senegal.

Although Maad Kumba Ndoffene Fa Ndeb was a devout follower of Serer religion and not a Muslim, he was the only one who came to the defense of Amadou Bamba, and told the French administration to release him at once as the accusations made against him are nothing but lies.

He described in Homeric manner all the nobility that surrounded the King in his ceremonies, and went on to talk about how Kumba Ndoffene Fa Ndeb once tried to trim his royal robes, which he [Senghor] still remembers in adulthood.

[8] Villalón writes: In 1983 Abdou Lahatte Mbacké, Bamba's son and successor as head of the Mouride order, came to Fatick personally to pay a visit to Farba Diouf in recognition of the service which the latter's father had performed for that of the former.

The visit rekindled close ties, and since that date Farba Diouf has regularly attended the grand màggal at Touba as a guest of the Mbacké family.
