Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned the following:
The special friends of Allah Ta‘ala who have acquired His recognition are such that, despite all the good qualities that they possess, they do not regard any of their actions to be worthy of being presented before Allah Ta‘ala. In proportion to the progress that they make, their humility goes on increasing, until they reach a point where they consider themselves to be the lowest of Allah Ta‘ala’s servants, and they feel that there is no servant of Allah Ta‘ala that is lower than them.
(Qutbul Aqtaab Hazrat Shaikhul Hadith Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) pg. 264-265)
