The works of Khoja Muhammad Porso played a crucial role in the common spread of Naqshband teachings, development of their theoretical and empirical sides and raising Naqshband teachings to a new stage in XIV-XV centuries. His spiritual heritage differs from other thinkers' works and heritage with its richness and productivity. More than 20 works of Khoha Muhammad Porso such as ''Qudsi words of tariqah sheikhs'' ("Tariqat mashoyixlarining qudsiy kalimalari''), ''Brochure about cult'' ("E'tiqod haqida risola''), ''Brochure about sufism terms'' (" Tasavvuf istilohlari haqida risola''), "Exegesis of Quran'' ("Qur'on tafsiri"), ''Forth Hadith'' ("Qird hadis''), ''Brochure about murids' propriety'' ("Muridlar odobi haqida risola''), ''Brochure about Kashf''("Kashf haqida risola''), ''Brochure about friendship''(''Dóstlik haqida risola''), ''Explanation to Fiqhi Kaydoni''(" Fiqhi Kaydoni asariga sharh''), ''Brief history of Makka''(" Qisqartirilgan Makka tarixi''), ''Six solutions''("Olti yechim''), ''Diamonds of sayings'' ("Hikmatlar javohirlari''), ''Khoha Muhammad Porso's letter to Mavlono Zaynuddin''(" Xója Muhammad Porsoning Mavloni Zaynuddinga maktubi''), "Khoja Bahouddin Naqshbandi's maqamat''(" Xója Bahouddin Naqshband maqomoti''), ''Introduction to Jamiu-l-Kalim''(Jamiu-l-Kalim kitobiga muqaddima''), ''Seventy two sects''("Yetmish ikki firqa''), ''Decisive decision for seeing friends''("Dóstlar vasliga yetishda hal qiluvchi qaror'') have arrived by now

The moral inheritance of Khoja Muhammad Porso interested orientalists, historians, Islamic scholars, mystic scientists in East and West. It is commendable that, Uzbek scientists carried out works relating to fields to a certain extent, but it is sad case that, philosophical aspects of mystical issues of the thinkers doctrine are not studied yet in philosophy. In this respect, the research of the doctrine of Khoja Muhammad Porso can give a chance to learn the degree of the theoretical study of philosophical-mystical issues in 14-15th centuries in Maverannahr related to the doctrine of mysticism and the doctrine of Naqshbandi and also to learn the themes related to this problem.

Especially, the famous book of Khoja Muhammad Porso which brought fame to him called 'Faslu-l-xitob bi vusuli-l-ahbob' served as a handbook about the issues of sharia and sect for Islam printers. At the moment, one of the copies of this book's manuscripts is kept in the museum of the Naqshbandi sect which located in the shrine of Bahouddin Naqshbandi. Book was copied twenty years after the death of Khoja Muhammad Porso and this copy contains 675 sheets written mixedly in Arabic and Persian. Professor G.N.Navruzova gives information that, the copies of this book are being stored in the fund of Institute of Oriental Studies in the form of 16 manuscripts, 17 lithographs and in the Ibn Sino museum in Bukhara region.

Hoja Muhammad Porso's great work that made him popular devoted to the Shari'a and the teachings is Faslu-l-khitab vusuli-l-ahbab ( A book that distinguishes people when it comes to finding friends). Over centuries, this great book has served as a vital guide, when any disputes came out among the Shariah, and the sects they relied on Faslu-l khitab vusuli-l-ahbab and Porsos ideas as an evidence of their opinions.

The work of Hoja Muhammad Porso is a source that allows us to distinguish black from white. Academician Aliybek Rustamov states that "If Hoja Muhammad Porso's work "Faslul Khitob" had been investigated, the motives of the various sects that went astray according to the Sharia would have been revealed" . And this statement confirms that the religious conflicts which had acted as a great threat at all times and the inhumane acts under the guise of religion have been a worthy blow. It is also necessary to study the legacy of the thinker in forming a sense of pride in their history,their ancestors, as well as in educating the younger generation to be comprehensively educated and spiritual.
