Biography

Imam Ali al-Ridha was the son of Imam Musa al-Kadhim and the eighth Imam. He is known for his vast knowledge and his debates with scholars of various religions and schools of thought. The Abbasid caliph al-Ma'mun forced him to move from Medina to Merv (in present-day Turkmenistan) and appointed him as his successor in an attempt to control the Shia community and legitimize his own rule. However, this plan was opposed by the Abbasid family. Before the succession could take place, Imam al-Ridha was martyred, allegedly poisoned by al-Ma'mun.

Understanding the significance of the fourteen infallibles in Shia Islam

Who are the 14 Masoomen?

In Shia Islam, the 14 Infallibles (Arabic: Chahārdah Maʿsūmīn) are the Prophet Muhammad, his daughter Fatima al-Zahra, and the Twelve Imams. They are considered to be divinely appointed guides who are free from sin and error.

These revered figures are central to Shia theology and spirituality, representing the unbroken chain of divine guidance and leadership after the Prophet Muhammad.

The concept of infallibility (ismah) in Shia Islam means that these 14 individuals are believed to be protected by God from committing sins or errors in matters of religious guidance.
