An interesting book contains more than eighty means of da'wah in different fields of our life such as da'wah at home, masjed, school and work in addition to various means of da'wah. These books teach us that we should not confine da'wah to masjed but it should far exceed it to include all life's fields. Based on these means of da'wah, we can direct da'wah to everyone by easy ways. We should know that da'wah is a responsibility of every Muslim, the issue which encourages us to use these means efficiently.
At a time in which the Muslims are beset with trials from every periphery and within, comes this heartening book rooted in the commandments of Allah (swt), the Sunnah and the excellent guidance and examples of the Muslims that have come before us. Don't Be Sad is an absolute must-read for all people. It is full of practical advice on how to replace sadness with a pragmatic and ultimately satisfying Islamic outlook on life. It exposes to the modern reader how Islam teaches us to deal with the tests and tribulations of this world.
