Sidi wa Sanadi Hazrat Moulana Mohammad Taqi Usmani db tells us,
That when his oldest brother Moulana Zaki Kaifi ra (father of Moulana Mehmood Ashraf Usmnai db) learned to write Urdu, the first thing he was instructed by his father to write was a letter to Hakeeul Ummat Moulana Ashraf Ali Thanwi quds sirrahu.
Hazrat Hakeemul Ummat ra replied encouraging him abundantly. He also instructed him that, ” now you should try to improve your hand writing with the intention that this will make it easier for people to read. See, that I am making you a Sufi you from this age.”
Correcting the intention and saving others from slightest discomfort are the essence of Tasawwuf.
