Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) narrates that the Noble Prophet (peace and blessings be upon him) said: "These four sisters are believers: Maymunah, Umm al-Fadl, Salma, Asma bint Umais. The last mentioned is the maternal sister (i.e., from the mother's side) of the first three."
