Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned the following:
There is one very important du‘aa which I make and many people are aware of this du‘aa. In fact, I ensure that I regularly make this du‘aa and never leave it out, whether I am in Makkah Mukarramah, Madeenah Tayyibah, India or anywhere else.
The du‘aa is, “O Allah, if I had inconvenienced any person, caused him any physical pain or verbally hurt him, then You out of Your infinite compassion, forgive me and reward the one whom I had hurt with such a compensation that is in accordance to Your greatness and position.”
This du‘aa is also recorded in the mubaarak hadeeth and is from among the du‘aas which Rasulullah (sallallahu ‘alaihi wasallam) himself made.
After mentioning this, Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) said, “May Allah Ta‘ala grant Rasulullah (sallallahu ‘alaihi wasallam) the highest stages of closeness and proximity to Him, for he had taught us a Deen whose teachings are so complete that nothing is left out.”
