Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once wrote the following to a certain person:
My beloved friend! The most important thing is for one to adhere to the sunnah of Rasulullah (sallallahu ‘alaihi wasallam) in all facets of his life to the best of his ability.
(Out of humility, Hazrat Shaikh [rahmatullahi ‘alaih] then mentioned regarding himself:)
This unworthy and impure servant is unable to follow the sunnah correctly. However, I have certain pious friends who are such that on hearing of their condition, I become extremely pleased. Many of my friends show great importance to upholding the sunnah, and they are making tremendous progress (in acquiring the special proximity of Allah Ta‘ala through practicing on the sunnah).
Another aspect which brings me great happiness and joy which you mentioned is that when you carry out any good deed, then your focus is not on the good deed, but rather you consider it only through the taufeeq of Allah Ta‘ala that you were able to carry out this good deed. For one to think in this manner is a great blessing and bounty of Allah Ta‘ala.
You should not worry about the negligence that overcomes you. Insha-Allah, through punctually engaging in the zikr of Allah Ta‘ala, your ghaflah (negligence) will gradually decrease.
Express immense gratitude to Allah Ta‘ala for His bounties upon you. Allah Ta‘ala has bestowed you with many of His special favours. Refrain from attributing any good deed to yourself. Every good deed which you carry out is a bounty from Allah Ta‘ala.
