Treatment for slack in performing Salat

A spiritual aspirant wrote to Hakeemul Ummah Shaikh Ashraf Ali Thanvi Rahimahullah, “My mind slacks in performing Salat.” i.e. My mind doesn’t get set for Salat and I don’t feel like praying Salat. Hakeemul Ummah Shaikh Ashraf Ali Thanvi Rahimahullah replied, “There is no harm in it (i.e. only such a reluctant state toward good deed could be usual). Just do not follow this slacking state. Oppose the unwillingness of your lower-self (the nafs) and accomplish Salat with due care. Also make a practice of saying some supererogatory prayers (i.e. Nafl Salat) up to a limit that would not hamper important works.” _{^{Islahi Majalis (3rd Part) by Mufti Taqi Usmani}}
