Jawshan Kabir

[1] Jawshan means "steel plate" or "mail" and thus the name of the prayer refers to Muhammad's heavy armor in battle.

According to Shi'i Muslims, during the war, the angel Gabriel came and brought him a message from God, teaching prayer to Muhammad to protect him from bad events.

[1] The context of the prayer was described by Ali al-Sajjad, the fourth Twelver Imam, and came to him from his great grandfather Muhammad by word of mouth.

Afterwards, a Twelver narrator and faqih, Ibrahim ibn Ali A’meli Kafa’mi, mentioned the Jawshan Kabir in his book Balad al-Amin.

Sabzevari has testified to Persian and Arabic poems based on prayer verses and has referred to Firoozabadi's dictionary of lexicon for lexical issues.

[2] Also, there are several hadiths from the prophet Muhammad that state that whoever recites this prayer will receive rewards in the world and Akhirah.
