Smile

It is the first arrow and the fastest of them all. It is like the salt for food. It is also regarded as a kind of worship and alms-giving as is mentioned in a hadith “Smiling at your brother’s face is as charity (Sadaqa)”. Abdullah ibn al Harith tells us about the Prophet (peace be upon him) saying that he had never seen someone smile at the other’s face as the Prophet Muhammad (peace be upon him) used to do.
