Be generous and forgiving even if someone does something without your permission or knowledge.

This hadith is about eating gifts while in ihram. Talhah bin 'Ubaidullah was given a bird as a gift while he was sleeping. Some of the people with him ate it, and when he woke up, instead of getting angry or scolding them for eating without his permission, he approved of their actions and said that they had eaten it with the Prophet Muhammad ﷺ. This teaches us to be generous and forgiving even if someone does something without our permission or knowledge. We should not get angry but rather show kindness by approving their actions instead. It also teaches us to be mindful when we are in ihram so that we do not break any rules unknowingly or unintentionally.
