Bahâeddîn Muhammad bin Muhammad Bukhârî ‘rahmatullâhi ta’âlâ ’alaih’ (718 [1318] - 791 [1389], Qasr-i-Ârifân, Bukhâra) was a great Walî and a great scholar in Tasawwuf.

Sayyid ’Abdulhakîm-i Arwâsî  ‘rahmatullâhi ’alaih’ said: “Rasûlullah ‘sall-Allâhu ’alaihi wa sallam’ had three tasks. The first one was to communicate and make known (tabligh) the rules of the Qur’ân al-kerîm, i.e. the knowledge of îmân and of ahkâm fiqhiyya, to all human beings. Ahkâm fiqhiyya is composed of actions commanded and actions prohibited. These two branches of knowledge make up the Ahkâm-i-islâmiyya. His second task was to transmit the spiritual rules of the Qur’ân al-kerîm, the knowledge about Allâhu ta’âlâ Himself and His Attributes into the hearts of only the highest ones of his Umma. His first task, tabligh, should not be confused with this second task. The lâmadhhabî, (i.e. people who deny the four Madhhabs,) reject the second task. However, Abû Hurayra ‘radiy-Allâhu ’anh’ said: ‘I learned two types of knowledge from Rasûlullah ‘sall-Allâhu ’alaihi wa sallam’. I have told you one of them. You would kill me if I explained the second one.’ These words of Abû Hurayra’s are written in the books Bukhârî, Mishqât, Hadîqa, and in the letters of Maktûbât, numbers 267 and 268. (English versions of the two letters can be read after this chapter.) The third task was directed towards those Muslims who did not obey the advice and sermons concerning carrying out the Ahkâm fiqhiyya. Even force was employed to get them to obey the Ahkâm fiqhiyya.
