Hazrat Mufti Mahmood Saheb (rahmatullahi ‘alaih) had a frame in his room in which “Ana ‘abdullah (I am the slave of Allah Ta‘ala)” was inscribed. This serves as a constant reminder that Allah Ta‘ala has the right to command and I have the duty to obey. This duty should be with beauty as well. That is we should carry out our duties happily and not grudgingly.
