The leader of the Naqshbandi sect, so called “Mujaddid Alf Thani” Ahmad Sirhindi writes:
“Following the advent of the Khatmur Rosul, Hazrat Muhammad Mustafa (peace and blessings of Allah be on him), the attainment of prophethood by one of his followers, as a subordinate and in service of the Holy Prophet, will in no way offend or be in conflict with his status as Khaatamur-Rosul. No doubts need be entertained in this regard."
