Hamdollah Mostofi and Dolatshah Samarghandi have mistakenly nicknamed Khajeh Abou Yaghoub Yousef Hamedani as Abou Yousef. This mistake has influenced the succeeding works as well. Unlike what the public think, Khajeh Yousef Hamedani was born in Bizani Jard(old name: Bouzanjerd) that is todays Hamedan. His tomb, presently a place of worship, can be found in the remains of the old city of Marv. Therefore referring to the city of Bayramali as Khajehs place of burial is a slip, which penetrated into the works of modern Iranian researchers due to Saeed Nafisis oversight.
Although the researchers have been doubtful about the position of Sanaee as a student of Khajeh, the two are likely to have met one another.
To date, the only masterpiece by Khajeh which has survived is the book entitled" Rotbatol Hayat". Recently part of the manuscript of the book " Al-kashf An Manazel Al-Saerin Ala Allah Azzevajal" of Khajeh has been found.
Moreover, according to evidence at hand, the manuscript of " Anvar-e-Hekmat" meaning" Rays of Wisdom" which has been recorded as a work of Khajeh in the national library does not belong to Khajeh at all.
