This is a letter written by Imam Ali (a) to Talha and Zubayr and sent to them through Imran bin Hasin Khuza\’i. Imran was a companion of the Holy Prophet (s). He had embraced Islam before the Battle of Khaybar and from then onwards he remained in his company. He was a very pious person and one of the very authentic narrators of the traditions of the Holy Prophet (s). Besides Nahjul Balaagha, this letter has also been narrated by Abu Ja\’far Iskaafi in his famous book "Al-Maqamat fi Manaqib Amir al-Mu\’minin".
