It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that when Allah, the Mighty and Majestic, revealed these verses: "And do not approach the property of the orphan except in the way that is best" [Surah al-An'am: 152] and "Indeed, those who devour the property of orphans unjustly (only fill their bellies with fire)" [Surah al-Nisa: 10] , whoever had an orphan in his care separated the orphan's food completely from his own food and the orphan's drink from his own drink. They would set aside some of the orphan's food, and it would remain there until he ate it, or it spoiled and was thrown away. This situation became very hard on them (the Companions), so they mentioned it to the Messenger of Allah (peace and blessings be upon him), whereupon Allah, the Mighty and Majestic, revealed this verse: "And they ask you about orphans. Say: Improving (their affairs) for them is best, and if you mix with them, they are your brothers" [Surah al-Baqarah: 220] . After that, they mixed their food and drink with theirs. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. Our Imams have cited it as evidence for the permission of al-munahadah, that is, sharing expenses jointly during a military expedition.
