Know that from this life, I’ll neither protect you from sun nor provide you material goods. I accept you if you follow God recommendations”. In this way, the contract started between Fall and Aamadu Bàmba Mbàkke. Ibrahima Fall became his 40th disciple. From this moment, Fall followed the "Ndiguel" "orders" of the Shaikh until Fall's death. Within this contract called “Diebelou”, Savishinsky claims that Ibrahima Fall displayed an absolute, slave-like devotion to his master. His “pastef” (courage and devotion) served example for all Mourides. In fact, Fall started “growing food, cutting firewood, fetching water and building shelters and mosques” (p. 213). Likewise, Serigne Moussa Kâ tells us that Fall reshaped quickly the relation between a disciple and his guide. Ibrahima Fall instituted five rules of deference to the Sheikh: Ibrahima Fall himself supervised these rules. In appearance, Ibrahima Fall had matted locks. Fall carried a black cudgel especially for making people respecting these rules. Fall also smoked a Western African plant called “pone”. Moussa Kâ claims that Fall often begged in neighbour villages with a wood bowl, which was an unorthodox practice. When Mame Chiekh Ibra Fall was taking a haircut, S.Touba told him not to take a haircut today, because it is not a day to take a haircut and he didn't take a haircut because he didn't have permission. In 1890, Shaikh Aamadu Bàmba nominated Fall the third responsible in the Mouride Brotherhood. Fall had to supervise all manual works. With the exile of Aamadu Bàmba Mbàkke, Fall's life changed. He moved to Saint-Louis, Senegal, to defend the innocence of his Shaikh. During Fall's negotiations with the French, Paul Marty recognised that Fall hid great intelligence. Another scholar cites the multiple Arabic poetries of Ibrahima Fall to prove Fall's intellectualism. Fall wrote also an Arabic book, "Jazbul Mouride". On 21 September 1895, the French exiled Aamadu Bàmba to Gabon. Aamadu Bàmba ordered Ibrahima Fall to work for Sherif Hassan. He did so until 1901, when Sherif Hassan died.
