Abu Azeez Ibn ‘Umayr Ibn Haashim was the brother of Mus’ab Ibn ‘Umayr and was fighting the Muslims on the battle of Badr. He was the holder of the banner of the kuffaar next to Al-Nadr Ibn Haarith. When he was taken as captive by the Muslims, he said:
“I was assigned to a group of the Ansaar. When they laid out their lunch or dinner, they would give me the bread while they themselves ate dates without bread. This was because of the Prophet’s instructions to them. Every time any one of them had a piece of bread, he would give it to me.
Sometimes I felt embarrassed by their hospitality and I gave the bread to any one of them who was around. He would return it without taking a single bite”
[Ibn Hishaam, As-Seerah An-Nabawiyyah, p. 209]
