Sheikh Ahmad Ardabili, popularly known as Muqaddas Ardabili (d. 993 AH) was an abstentious and practicing scholar, and lived contemporaneous to scholars such as Sheikh Bahaai, Mulla Sadra and Mir Damaad. His grave lies within the holy shrine of Imam Ali (a.s.) in the city of Najaf. It has been reported that once a person had come to Najaf for pilgrimage and not recognising him, had requested him to wash his clothes.
Muqaddas agreed and after washing it, brought it to the pilgrim. It was at this point that the pilgrim happened to become aware of his identity and felt greatly embarrassed at his own behaviour, and the people too rebuked him for his conduct. Muqaddas, however, said:
Why do you censure him? Nothing (significant) has happened. The rights of brethren-in-faith are far more than what I have done for him( Muntakhab al-Tawarikh, p. 181. )
