Extend hospitality for three days and give charity when possible.

This hadith teaches us the importance of hospitality and generosity. It encourages us to be kind and welcoming to our guests, as hospitality should be extended for three days. Anything beyond that is considered charity, which is a noble act in Islam. We should strive to make our guests feel comfortable and welcome in our homes, as this will bring blessings from Allah SWT. Furthermore, it also teaches us the importance of giving charity; even if we are unable to extend hospitality for more than three days, we can still give charity in order to help those who are less fortunate than ourselves.
