This hadith has been transmitted on the authority of Ibn Abbas with a slight variation of wording.
The Prophet Muhammad ﷺ said “He who has been endowed with kindness has been endowed with good” [Sahih Muslim]. This means that when someone shows kindness towards another person or creature, they will receive blessings from Allah SWT in return for their good deed. Furthermore, the Prophet ﷺ said “The most beloved of people according to Allah is he who brings most benefit to people” [Sunan Abu Dawud]. This means that those who are generous and kind towards others will be rewarded by Allah SWT for their efforts in helping others.
