Ja'far al-Sadiq
Abdullah al-Aftah ibn Ja'far al-Sadiq (d. 766 CE / 149 A.H.) was the eldest son of Ja'far al-Sadiq (after al-Sadiq’s death) and the full-brother of Isma'il ibn Jafar. Abdullah’s title ""al-Aftah" derives from the Arabic words "aftah al-ra’s" (broad-headed) or "aftah al-rijlayn"" (broad-footed) used to describe his appearance.
