Salit ibn Nu'man

Ṣalīṭ ibn Nuʿmān was a Muslim who had secretly accepted Islam while remaining in Makkah, keeping his conversion hidden from the Quraysh. At the time, wine had not yet been prohibited in Islam, so he continued to socialize with his pre-Islamic companions. One of those companions was a member of the elite inner circle of Quraysh involved in planning the alternative caravan route (the Iraq route) after the disaster of Badr. While drinking wine together, this companion became boastful and disclosed to Ṣalīṭ the entire top-secret plan: the Quraysh caravan, led by Ṣafwān ibn Umayyah, was going to take an unprecedented eastern route far around Madinah to reach Syria safely. As soon as Ṣalīṭ heard this, he immediately sent a message to the Prophet ﷺ informing him of the route. The Prophet ﷺ was thus able to dispatch Zayd ibn Ḥārithah to intercept the caravan at the watering place of Qarada, capturing the entire caravan with zero Muslim casualties. This was a direct fulfillment of Allah's promise at Badr that the Muslims would receive 'one of the two groups.'
