It is narrated from Sayyiduna Rifa'ah bin Rafi' bin Malik (may Allah be pleased with him): On the day of Badr, people gathered around Umayyah bin Khalaf (to kill him). I too advanced towards him and saw that a piece of his armour had been cut away beneath his armpit. So I struck him there with my sword a blow that cut him down. Likewise, on the day of Badr I was hit by an arrow which destroyed my eye; the Messenger of Allah (peace and blessings be upon him) put his blessed saliva in it and prayed for me, and after that it never caused me any pain. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.
