The famous book Don't Be Sad (en Español) has been translated in the Spanish language.

This heartening book rooted in the commandments of Allah (swt), the Sunnah and the brilliant guidance and examples of the Muslims, comes at a time in which the Muslims are overwhelmed with trials from every periphery and within.

Don't Be Sad is an absolute must-read for all people, which states practical advice on how to replace sadness with a realistic and ultimately satisfying Islamic outlook on life. It exposes how Islam teaches us to deal with the tests and tribulations of this world, to the modern reader.

So, take heart and hold firmly onto the rope of Allah (swt).
