Be generous and charitable towards others; Use your wealth for good causes such as helping those in need; Donate money for charity work; Appoint people to look after the needs of people; Open up doors of mercy upon yourself by being kind and compassionate towards others.

This hadith teaches us about the importance of helping those who are in need. The Prophet Muhammad (PBUH) taught that if an Imam or leader closes their door on someone who is poor and struggling with dire straits or poverty, then Allah will close the gates of Heaven from them. Mu'awiyah was so moved by this teaching that he appointed a man to look after the needs of people and help those who were struggling financially. This hadith encourages us to be generous and charitable towards others as it is a way for us to gain rewards from Allah SWT and open up the doors of His mercy upon us. It also teaches us not to be selfish with our wealth but rather use it for good causes such as helping those in need or donating money for charity work.
