[ALLAH’S Quran 4:86] “When you are greeted with words or gestures, acknowledge the greeting with a more courteous recognition or at least return the same formula; it is an obligation. Allah has always taken account of all things and all actions.”

The Prophet (peace be upon him) has said: [Malik’s Muwatta, Volume 47, Hadith 16] “The Prophet Muhammad (peace be upon him) said: “Shake hands and rancor will disappear. Give presents to each other and love each other, and enmity will disappear.”
