One day, a group of young men from the tribes of Aws and Khazraj (two tribes from `Arabia that had been at war for countless years, however under the shadow of Islam and true faith, were able to come together as brothers of one another and have love rule between them both) were sitting together.
A Jew from Madinah named Shas ibn Qais who was very jealous of the unity that had been brought about between these two tribes, entered into their gathering and through the shrewdness that he possessed, started to speak about and remind them about the bitter moments that had transpired between these two tribes during the battle of Ba`ath before the coming of Islam. He spoke in such a manner that he was able to instigate the youth of both tribes to reach for their swords causing them to re-ignite the war of Ba`ath.
The Prophet (blessings of Allah be upon him and his progeny) was informed of what was transpiring and he himself went to this gathering and gave a speech in which he mentioned, “Islam made you brothers of one another and commanded you to remove any form of hatred or grudges that remain in your heart.”
When the speech of the Prophet reached to this phase, the deafening sound of crying and weeping could be heard and in order to attest to the religious brotherhood that existed amongst themselves, they began to hug each other and asked Allah (Glorified and Exalted is He) for forgiveness.
Today there are many Shas ibn Qais in our society……..
