Al-Jawshan al-Kabir Supplication
Al-Jawshan al-Kabīr (Arabic:الجوشن الکبیر) is a supplication cited from the Prophet (s). The supplication includes 100 sections containing 1001 names and attributes of God. The supplication was revealed to the Prophet (s) by Jabra'il (Gabriel). Today in Iran, this supplication is an essential part of Laylat al-Qadr rituals for Shiites. Some people write the supplication on their shrouds, as recommended by some hadiths.

Hence, this is the reason for its appellation, "al-Jawshan al-Kabir" (the great armor).
The supplication has 100 section, each containing 10 of divine names and attributes, except for the 55th section that contains 1
