Hazrat Muneeb Ghaamidi (radhiyallahu ‘anhu) relates, “I once observed Rasulullah (sallallahu ‘alaihi wasallam) addressing people and saying to them, ‘O people! Say Laa ilaaha illallaah, you will be successful.’ However, some wretched people were hurling abuse at him, some were spitting at him and others were flinging sand at him. They continued in this manner until the afternoon, when a young girl carrying water arrived and washed the blessed face and hands of Rasulullah (sallallahu ‘alaihi wasallam). When I enquired as to who the young girl was, I was informed that she was the daughter of Rasulullah (sallallahu ‘alaihi wasallam), Hazrat Zainab (radhiyallahu ‘anha).”
