In page Sibghatullah Mojaddedi:

"

Mojaddedi studied Islamic Law and Jurisprudence at al-Azhar University in Cairo, Egypt. In 1952 he returned to Afghanistan to teach in high schools and at Kabul University, where he became known as an advocate of Afghan independence.[2][3] In 1959 Mojaddedi was accused of conspiring against then Soviet Prime Minister Nikita Khrushchev and was imprisoned until 1964.[2] In 1973 he was forced into exile for his outspoken comments regarding Soviet influence in Afghanistan. Following the Saur Revolution in 1978, the new communist government killed Mojaddedi's brother and several of his relatives.[8] His period in exile was spent in several countries such as Denmark and Pakistan before his entry into Afghan politics.[2][3]
