Does this hadith exist? What is its source?
The Prophet Muhammad (peace be upon him) taught us that the best deed after believing there is no deity worthy of worship except God is "benevolent love towards people".
The Arabic is al-tawaddudu ila al-nas. Which literally means love towards the people/humanity.
