Mohamed Atta
Atta was born on September 1, 1968, in Kafr el-Sheikh, located in Egypt's Nile Delta region. His father, Mohamed el-Amir Awad el-Sayed Atta, was a lawyer, educated in both sharia and civil law. His mother, Bouthayna Mohamed Mustapha Sheraqi, came from a wealthy farming and trading family and was also educated. Bouthayna and Mohamed married when she was 14, via an arranged marriage. The family had few relatives on the father's side and kept a distance from Bouthayna's family. In-laws characterized Atta's father as "austere, strict, and private," and neighbors considered the family reclusive. Atta was the only son; he had two older sisters who are both well-educated and successful in their careers — one as a medical doctor and the other as a professor.
Musa al-Sadr
His great-great-grandfather S. Salih b. Muhammad Sharafeddin, a high-ranking cleric, was born in Shhour, a village near Tyre, Lebanon. Following a frantic turn of events related to an anti-Ottoman uprising, he left for Najaf. Sharafeddin's son, Sadreddin, left Najaf for Isfahan, which was then the most important centre of religious learning in Iran. He returned to Najaf shortly before his death in 1847. The youngest of his five sons, Ismail ("as-Sadr"), was born in Isfahan, in Qajar-ruled Iran, and eventually became a leading mujtahid.
