He was very regular with morning walk. He devoted all that time to the remembrance of Allah and supplications, for which he had formulated a map and a sequence in his mind.
He told me several times that by the time he reached a spot or turning during the walk, he had recited Darood so many times or supplicated in particular words so many times. If it was raining after Fajr, he used to walk around in the Mahmood Hall for the same duration as his daily walk.
Thus, by completing the specified number of supplications and tasbihat he could also guess the distance he had covered.
I recall an interesting thing that he told me in connection with his walk. He said that an Englishman of such and such appearance crossed him every morning at the same spot, and they exchanged “good morning” wishes. He added: “He seems to be very punctual.” Then he smiled and said: “I am no less than him!”
