Tughluq was a strict Muslim, maintaining his five prayers during a day, used to fast in Ramadan. According to 19th Century CE British Historian Stanley Lane-Poole, apparently courtesans had hailed Tughluq as a "man of knowledge" and had interest in subjects like philosophy, Medicine, mathematics, religion, Persian and Urdu/Hindustani poetry. In his "Medieval India", "He was perfect in the humanities of his day, a keen student of Persian poetry.........a master of style, supremely eloquent in an age of rhetoric, a Philosopher trained in Logic and Greek metaphysics, with whom scholars feared to argue, a Mathematician and lover of science." Barani has written that Tughluq wanted the traditions of the nubuwwah to be followed in his kingdom. Even though he did not believe in mysticism, Chandra states that he respected the Sufi saints, which is evident from the fact of his building of the mausoleum of the saint Nizamuddin Auliya at Nizamuddin Dargah. Critics have called him hasty in nature, owing to most of his experiments failing due to lack of preparation. Ibn Battuta has also written that he depended on his own judgement and rarely took advice from others and has also criticized him for his giving of excessive gifts and "harsh punishments". He was famous because whenever a gift was bestowed upon him, he would give gifts worth three times the value to show his stature.
