The biographies of the Sahabah contain the history of men who accepted the invitation of Islam when it was presented to them. Their hearts testified to its truth and all they said when they were called towards Allaah and His Rasool SAW was, "Our Rabb, we have certainly heard the caller (Rasulullaah SAW) calling to Imaan (saying), 'Believe in your Rabb!' so we believedN(').They placed'their hands in the hands of Rasurullaah SAW and it became easy for them to sacrifice their lives, their wealth and their families. They then began to find pleasure in the difficulties and hardships that afflicted them in the course of calling others towards Allaah. In this manner, conviction permeated their hearts and gained mastery over their bodies and their minds. They displayed the wonderful belief in the unseen, undying love for Allaah and Rasulullaah SAW compassion for the Mu'mineen and sternness towards the Kuffaar.
