Hakīmul Ummat Maulānā Ashraf ‘Alī Thānwī A Biography Volume Two
“Whenever Hadrat Wālā goes to his houses, he first knocks on the door and then calls for someone by name. He continues waiting outside until he is called from inside. If a child calls him in, he does not consider it sufficient. He does not enter the house until an adult calls him in. Since he does not like to cause the slightest inconvenience to anyone, if he perceives that the womenfolk are hastening to go into purdah, he calls out with genuine kindness: “There is no need to rush. You may go into purdah at ease, I am waiting.” ”
