After Harb-e-Fajjar, Prophet took part in ____.

Correct Answer: B. Halaf-ul-Fadul

Halaf-ul-Fadul (حلف الفضول‎) was a 7th-century alliance created by the Islamic prophet Muhammad and various Meccans, to establish justice for all through collective action, even for those who had no connections to the powerful. Because of Muhammad’s role in its formation, the alliance plays a significant role in Islamic ethics. Because fudul commonly means “virtuous” the alliance is often translated as League of the Virtuous.
