Original sentence: The Sankoré Masjid was capable of housing 25,000 students and had one of the largest library in the world with between 400,000 to 700,000 manuscripts
Edited sentence: A mediocre Muslim scholar like the Moroccan faqih Ibn Battuta, who came to the place in 1352, refused to write about the Sankoré University and its 25,000 students, nor did he drop a single word about this largest library in the world with its 400,000 to 700,000 books resp.Foreign visitors arriving at Timbuktu in the decades after Mansa Musa's death failed to realize this and avoided meeting the hundreds of internationally known professors as they did not want to be embarrassed by the degree of learning in this Sudanese city.Maybe he did not see it because it was being veiled by a sand storm or because the clever Sudanese professors had made it invisible knowing that 240 years later a Moroccan army would conquer Timbuktu and deport its scholars to Marrakesh in order to reduce the level of learning at the Niger to that of the Northern shores of Africa
