The Sherif and Muqaddam Sidi Abou Abdallah Sidi Musa ibn Mazuz (may ALLAH be pleased with him) was one of pillars of this Tariqa. His feet were firmly rooted in this noble path. He was holder of elevated aspiration. He had an authentic spiritual opening and powerful unveiling. He was among the ten people to whom the Prophet (peace and blessings be upon him) had guaranteed the Great Opening, as Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret) had announced.

It is said that Sidi Musa Ibn Mazuz (may ALLAH be pleased with him) asked many questions of Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret) because he was earnestly researching, and some of the elite among the companions feared for him for this lack of propriety (Adeb). One day, when he rose from sitting with Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret), the sincere beloved Sidi Mohamed Salassi (may ALLAH be pleased with him), who was older than Sidi Musa Ibn Mazuz, said to him: “O Sidi Musa, I fear for you when you are setting with Seyyidina because of your persistent questions, which is a lack of propriety for a disciple regarding his Sheikh.” He continued in the same way until Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret) called them both before him. They obeyed this order immediately and when they came before Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret), he said to Sidi Mohamed Salassi (may ALLAH be pleased with him): “What have you got against Sidi Musa?” Know that he is loved by us whatever his situation.” Since that day, everytime he met him, he used to say: “O Sidi Musa, have no fear, for you are among the beloved.”

Numerous prodigies and wonders have been related about him. One day, he was sitting at home in Fes, a kitten came through the door and began to mew pacing up and down and backwards and forwards. So Sidi Musa ibn Mazuz (may ALLAH be pleased with him) said to his son: “Get up son and take this kitten back to such and such house in Sa’oud street that it is where it comes from, it told me so.” He was surprised but obeyed his father. He left the kitten in front of the house in question the kitten was happy. As he was leaving, the house, the son heard a voice coming from inside the house: “This is the kitten that we had abandoned in such and such place and here it is again. How has it been able to find its way home despite the great distance?”

Sidi Ghali, the son of Sidi Musa ibn Mazuz (may ALLAH be pleased with them both) said that his father had told him: “There are people who hear every single hair on their body evoking ALLAH The Most High, and when they sleep, their spirit go to join the Prophet (peace and blessings be upon him).” When his father died, he told this to the knower Sidi Muhammad ibn Ghazi (may ALLAH be pleased with them both) who revealed: “Know that in reality he was referring to himself and I was aware of his situation.”

Sidi Musa Ibn Mazuz (may ALLAH be pleased with him) was firm and determined. He never allowed anyone who was not in a pure state sit in the Wazifa line. He used to say: “I heard Mawlana Sheikh saying: “Keep people in a state of impurity away from the ranks of the Wazifa.”” Likewise, Sidi Musa allowed no one to sleep in the Zawiya except visitors or guests, but not more than three days. If a merchant wanted to stay longer, He would sent him to the fondouq (Hotel reserved for the merchants). If a student wanted to stay more, and wanted to learn knowledge, he sent him to the madrassa. If he saw someone in possession of tobacco, he removed him from the Wazifa circle, in accordance with the following words of Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret): “If you find a person in possession of tobacco whilst attending the Wazifa gathering, take him outside.”

Sidi Musa Ibn Mazuz (may ALLAH be pleased with him) scrupulously avoided stretching out his legs towards poetic verses, paying homage to Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret), engraved on certain walls of the Zawiya, and he reprimanded those who did. One of the great companions said to him: “O Sidi, they are high-ranking.” He replied: “And even if they are?”

Sidi Musa Ibn Mazuz (may ALLAH be pleased with him) was among those who travelled to the desert to visit Seyyidina Ahmed Tidjani (may ALLAH sanctifiy his precious secret) before he emigrated to Fes. He passed away in 1257 of the hegira.
