Jawshan Kabeer is a long Islamic prayer that contains 1001 names and attributes of God. Jawshan means "steel plate" or "mail" and thus the name of the prayer refers to Muhammad’s heavy armor in battle. According to Muslims, God taught the prayer to him as a protection from injuries in war, instead of hard armor. The prayer was codified by Ali ibn Husayn Zayn al-Abidin and mentioned in Balad al-Amin.
The Islamic prophet Mohammed used hard and heavy armor during fighting in the war. Because of the tightness of his armor, his body was injured. According to Muslims, during the war, the angel Jibra'il (Gabriel) came and brought him a message from God, teaching prayer to Muhammad to protect him from bad events. Jibra'il said: "O’ Muhammad! Your God conveys his salutations to you and has said to take this coat of armor and to recite it as this is a protection for you and your Ummah."The prayer became his armor to protect him against injuries. The name of the prayer was taken from Muhammad’s heavy armor (Jawshan) in the battle.
