The venerable Sheikh Ould Khayri was Born in Zarariya, on Sha' ban 22nd, in 1373 Hijra, which corresponds to April 26th, 1954 in the greguorian calendar. His birth coinceded with the third visit that Mawlaanaa Sheikh Ibrahima Niass made in Mauritania.
The first time Mawlaanaa Sheikh Ibrahima Niass visited Mauritania was between 1948 and 1949. The most official visits took place in 1952 (the year during which he wrote his poem entitled Rihlatu Guannaria) and 1967.
During each of these years , Elhadj Ibrahima Niass paid many of his followers some visits, who were scattered in different villages, out-settlements and towns.
His last, shortest and less famous visit, took place in 1970 in Nouadhibou, where he had an audience with his majesty Hassan II (1928 - 1999), the King of Morocco of that time, who was in delegations with other presidents such as, the Algerian Mohamed Ben Brahim Boukharouba alias Houari Boumediene (1932 - 1978), the Tunisian Habib Bourguiba (1903 - 2000) and Moctar Ould Daddah, the president of the Islamic Republic of Mauritania (1924 - 2003).
Those maghrebian leaders above-mentioned wanted to find a common ground as far as the Western Sahara , which was under the yoke of Spain , was concerned.
On Monday , April 26th 1954 , the wish of Sayda Fatoumetou Zahra Mint Add , which was to give birth with the presence of Sheikh Ibrahim Niass, had occurred in a very particular way.
Seydi Muhammad Mishriy Ould Hadj , one of the first Mauritanian followers of Baye Niass , a real Sufi , the most knowledgeable about the esoteric science of Islam or Ma'rifa, gave the new-born to Sheikh Baye Niass.
The latter chewed one date and put it in the mouth of the baby, then he suggested it to be named after Sheikh Ibrahim.
Undoubtedly, the last but one son of Da'iya (mother of Sheikh Ould Khayri) hasn't been an ordinary man.
His father Sidy Ould Khayri whose nickname is Di (1900 - 1991), was gifted in mystical sciences; the miracles he used to do are engraved in the memories of those who had a chance to make his acquaintance. Even though he had a very high spiritual rank, Sidy Muhammad Ould Khayri decided to be affiliated to the Fayda and became a very dedicated follower of Sheikh Ibrahim Niass, the same as our saint mother, his wife and mother of Sheikh Ould Khayri, Sayda Fatoumétou Mint Add (Da'iya).
Sayda Fatoumétou is a sister of Abdallah Ould Abdallah, Seydi Ahmed Ould Add alias Oustaz (the great teacher and former rector of the mosque and Zawiya of Mata-Moulaana ; he is now the Imam of the saints place & holy village of Boubacar), Ahmed Mahmoud Ould Eybe and Aichétou Mint Mouhamdi Ould Beddi.
The Khayri family belongs to the Idaw ' Ali tribe which originates from Seydi Hassan Ibn Fatoumata Bint Rassulullah (saws), one branch from the Ahlul Bayt, which is highly considered and well-known in Mauritania, mainly in the region of Boubacar, which is named after Boubacar Ben Ali, the former emir of Trarza.
It's thanks to Sidi Muhammad al-Hafiz ash-Shinqiti (ra), who is part of the Idaw'Ali tribe, that the Tariqa Tijani became so widespread in Western Africa.
Sheikh Ould Khairi, who benefitted from the sympathy of his family environment, particularly the one he received from his brothers and sisters such as Seydi Muhammad Yahya, Seydi Muhamdi and Seydi Muhammad Lamine, dedicated most of his time in reading the Holy Qur'an and meditating.
It was almost impossible to see him entertaining himself or playing with kids at the same age as him, and most importantly, he was very close to Sheikh Baye Niass, the spiritual guide, that he met and chose for himself right in the year 1968, the year of his affiliation to the Tariqa Tijaniyya.
