[7] This event is mentioned in Ibn Hisham's biography of Muhammad, and other historical sources.
[1][8][9][10] A month after the Invasion of Sawiq, Muhammad learnt that some clans of the Ghatafan tribesmen had gathered troops at Dhu Amar in Nejd.
[4] According to the Muslim scholar Sami Strauch, it is reported in Sahih Bukhari that it was raining, and Muhammad took his garments off and hung them on a tree to dry, while the enemy was watching, Ghwarath ibn al-Harith went to attack Muhammad.
Then according to Muslim scholars the Angel Gabriel came and thumped Ghawrath in the chest and forced him to drop his sword.
"[4] Ghawrath replied: "No one, and I testify there is no God worthy of worship but Allah" and he then converted to Islam.
Allah's Apostle did not punish him (for that)"Sahih al-Bukhari, 5:59:458[4] This incident is also mentioned in Ibn Sa'd Kitab Al-tabaqat Al-Kabir, Volume 2.
