"The Prophet (ﷺ) set out for the battle of Dhat-ur-Riqa' at a place called Nakhl and he met a group of people from Ghatafan, but there was no clash (between them); the people were afraid of each other and the Prophet (ﷺ) offered the two raka'at of the Fear prayer."

Narrated Salama: "I fought in the company of the Prophet (ﷺ) on the day of al-Qarad."
Sahih al-Bukhari Book 64, Hadith 171
