A senior murid wrote,

“How should I treat any negligence in my daily wird (ma’molat) and delay in writing to you a letter (regarding my current spiritual state)?”

Hadhrat Mufti Rasheed Ahmad Ludhyanawi (may Allah have mercy on him) replied,

“For being negligent in any wird  pray two units (raka’h) of nafil salah and for delay in writing a letter fast for a day (as a penance).”

Sayyidi wa murshidi, page 138

P.S. Writing a letter/email to the Shaykh is essnetial in Ashrafiya tariq. Hadhrat Sayyidi wa sandi Mawlana Mohammad Taqi Usmani (may Allah preserve him) recommends to write a letter regularly, atleast once a month.
