Allah's Messenger (ﷺ) said, "Tomorrow I will give the flag to a man with whose leadership Allah will grant
(the Muslim) victory." So the people kept on thinking the whole night as to who would be given the
flag. The next morning the people went to Allah's Messenger (ﷺ) and every one of them hoped that he would
be given the flag. The Prophet (ﷺ) said, "Where is `Ali bin Abi Talib?" The people replied, "He is
suffering from eye trouble, O Allah's Messenger (ﷺ)." He said, "Send for him and bring him to me." So when
`Ali came, the Prophet (ﷺ) spat in his eyes and invoked good on him, and be became alright as if he had
no ailment. The Prophet (ﷺ) then gave him the flag. `Ali said, "O Allah's Messenger (ﷺ)! Shall I fight them (i.e.
enemy) till they become like us?" The Prophet (ﷺ) said, "Proceed to them steadily till you approach near
to them and then invite them to Islam and inform them of their duties towards Allah which Islam
prescribes for them, for by Allah, if one man is guided on the right path (i.e. converted to Islam)
through you, it would be better for you than (a great number of) red camels."
Sahih al-Bukhari Book 62, Hadith 51
While the Prophet (ﷺ) was prostrating, surrounded by some of Quraish, `Uqba bin Abi Mu'ait brought the
intestines (i.e. Abdominal contents) of a camel and put them over the back of the Prophet. The Prophet (ﷺ)
did not raise his head, (till) Fatima, came and took it off his back and cursed the one who had done the
harm. The Prophet (ﷺ) said, "O Allah! Destroy the chiefs of Quraish, Abu Jahl bin Hisham, `Utba bin
Rabi`al, Shaba bin Rabi`a, Umaiya bin Khalaf or Ubai bin Khalaf." (The sub-narrator Shu`ba, is not
sure of the last name.) I saw these people killed on the day of Badr battle and thrown in the well
except Umaiya or Ubai whose body parts were mutilated but he was not thrown in the well.
Sahih al-Bukhari Book 63, Hadith 79
