Shaykh Ibrahim Niass is the only Tijani Shaykh to ever publish a Tafsir of Quran in its entirety. He completed the entire Tafsir of Quran between 10 and 12 times throughout his life, in public. Most of the times he would engage in the Tafsir, it would be in the Wolof language, but 2 or 3 times he did the entire Tafsir in the Arabic language for the benefit of his non-wolof speaking Murids (Students).
The very last time he did the entire Tafsir in public, was in the year 1963 and it was recorded on cassette tape.

One of his senior students from Mauritania named Shaykh Muhammad Wuld' Abdallah al-Jayjuba was present for all of his Tafsir readings and took the great task of transcribing the final recorded Tafsir into book form. It took him over 30 years to edit and check all of the Hadith and sources that Mawlana Shaykh Ibrahim Niass used in the Tafsir. The total number of Hadith that Shaykh Ibrahim mentioned in the Quran are over 6000.

Shaykh Ibrahim Niass is known to have completed (Khatmul-Quran) recitation of the entire Quran twice a week.
In one of his famous poems he beseeches Allah to "Make the memorization of Quran his Karama (Miracle)."

When Shaykh Ibrahim Niass wanted to publicly give Tafsir Quran for the first time, he requested from his older brother to borrow his copy of Tafsir Jalalayn. That request was refused and Shaykh Ibrahim said...."I only ask for Tafsir Jalalayn as a formality and Adab" In other words, he did not need it. (In those days, the Shuyukh would borrow Tafsir from each-other because it was so rare to have it in a book form)
In Reality, Shaykh Ibrahim Niass did not learn Tafsir from anyone besides Allah himself.
His brother sent spies to listen to SHaykh Ibrahims Tafsir and report back as to what he was saying since he did not have the Tafsir Jalalayn to help....The spies reported back that what they heard from Shaykh Ibrahim was so amazing that they could not stay away. They said that they heard knowledge that even the Shaykhs father did not have or explain before. They testified that Shaykh Ibrahim was indeed a Master without comparison.
This Tafsir is a Jewel that contains the meanings of the Zahir (Outward) and Batin (Inward/Hidden) explanation of the Quran.

Our Master and Seal of Muhammadan Sainthood Mawlana Shaykh Ahmed Tijani as-Sharriff has said in his Jawahir al-Ma'ni...."The Zahir and Batin meanings of Quran are Haq (Truth) and they don't contradict each-other."
