A person once wrote a letter to Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih), complaining of numerous problems that he was experiencing in relation to Deeni and worldly matters. In reply, Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) wrote the following:

After adopting the correct means, entrust all your affairs to Allah Ta‘ala. Thereafter, whatever Allah Ta‘ala decides for you, you should remain entirely pleased and satisfied with His decision. This is the best solution that one can adopt for all types of problems and anxieties. (Malfoozaat Hakeemul Ummat 23/195)
