Undoubtedly, the heart leans towards those who are kind and gentle. It was said a long time ago: "Make your face happy and your words gentle, and you will be more beloved to the people than those who give them a gift".

Adorning himself with kindness and gentleness helps to achieve that goal with the grace of Allah.
