The Only Creation Of Allah Who Has Been Given The Ability To Smile Is A Human Being. No Bird No Animal No Fish No Reptile Can Smile. They Can Show Teeth But Not Smile. Smile Involves A Chemical In The Brain Called SEROTONIN And SEROTONIN Is Only Found In Human Beings.
So Use Your Gift Of SMILE More Often. Smiling Is A Way Of Being Thankful To Allah And A Way Of Making Others Happy Around You. #MirMak
