Once Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) mentioned:
These sublime etiquettes which I have prepared regarding interacting and socializing with people are in reality the sublime etiquettes of Islam. These etiquettes are explained in order to bring ease and comfort to people and save them from the least amount of inconvenience. Some people are under the impression that Muslims have adopted these sublime etiquettes from the West. This is totally incorrect; rather the West only discovered this from Islam. How unfortunate it is that today we have regarded our legacy as the wealth of others. (Malfoozaat Hakeemul Ummat 1/228)
