Mukhtasar Muslim

Sayyiduna Umar bin Khattab (may Allah be pleased with him) says that I heard the Messenger of Allah (peace and blessings be upon him) say: Among the Tabi‘in, there is a best person whose name is Uwais. He has a mother (meaning, among his relatives, only his mother will be alive) and he will have a whiteness (i.e., a skin condition). You should ask him to pray for you.
