Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعنه قال: قال رسول الله صلى الله عليه وسلم: "رب أشعث أغبر مدفوع بالأبواب لو أقسم على الله لأبره " ((رواه مسلم)).
Messenger of Allah (ﷺ) said, "Many a person with shaggy and dusty hair, dusty and driven away from doors (because of their poverty and shabby clothes) were to swear by Allah (that something would happen), Allah will certainly make it happen".[Muslim].
