One of the questions Heraclius asked Abu Sufyan, who at that time was a staunch opponent of Islam, regarding Rasulallah s.a.w was:
‘Are his followers increasing or decreasing (day by day)?’
To which Abu Sufyan replied, ‘They are increasing.’ 
Despite all tactics hostile disbelievers employed to stop Rasulallah s.a.w., his s.a.w. followers kept on increasing.
Despite all of the Islamophobia and their skewed efforts to turn people away from Islam, its followers continue to grow.
Despite all of the media painting Islam negatively,
Despite some of us Muslims not doing a very good job in representing Islam in our interactions and daily activities,
Despite everything that seem to be going against us…
Islam is still the fastest growing religion.
This is a sign of the truth of the Message.
And this is only from the tawfiq and divine help of Allah s.w.t.
