Abu Talha and the Prophet (ﷺ) used to shield themselves with one shield. Abu Talha was a good archer, and when he threw (his arrows) the Prophet (ﷺ) would look at the target of his arrows.

← Previous Hadith While some Ethiopians were playing in the presence of the Prophet, `Umar came in, picked up a stone and hit them with it. On that the Prophet (ﷺ) said, "O `Umar! Allow them (to play)." Ma`mar (the subnarrator) added that they were playing in the Mosque.

Sahih al-Bukhari Book 56, Hadith 115 Next Hadith → When the helmet of the Prophet (ﷺ) was smashed on his head and blood covered his face and one of his front teeth got broken, `Ali brought the water in his shield and Fatima the Prophet's daughter) washed him. But when she saw that the bleeding increased more by the water, she took a mat, burnt it, and placed the ashes on the wound of the Prophet (ﷺ) and so the blood stopped oozing out.
