Shaykh Jamal-ud-din Ahmad Hansvi (d.1261) a senior khalifa of Baba Farid-ud-din Ganj Shakar (Allah Have mercy on them) wrote in his compilation of spiritual revelations,
Apostate are of two kinds.
One of Shariat and the other of tariqat (Tasawwuf).
The apostate in Shariat is the Muslim who renounces Islam.
In tariqat the disciple who disobeys the instructions of his Shaykh is an apostate of tariqat.’
