Which is the 11th month of Islamic Calendar?

1. Rabi-ul-Awwal
2. Safar
3. Dhu al-Qa'dah
4. Shawwal

Dhul Qa’dah is the eleventh month of the Islamic calendar. It is one of the four sacred months (al-ashhur al-hurum) during which warfare is prohibited. The name means “possessor of sitting” or “month of truce,” as Arabs would cease fighting and sit peacefully in their homes during this period. Dhul Qa’dah precedes Dhul Hijjah, the month of Hajj pilgrimage, and serves as a preparatory month.
