Hearing that al-Harith bin Dirar is gathering men to attack Madinah, the Prophet ﷺ marches to the well of al-Muraisi’ and defeats Banu al-Mustaliq. Among the captives is Juwairiyah, the chief’s daughter. On the march, the hypocrites under ‘Abdullah bin Ubayy try to set the Emigrants and Helpers against each other.
As the book dates it: Sha’ban, 6 A.H.
