History has proven that unition is THE option for us.

Before Islam the Arab tribes where scattered and useless. When united they formed an unresistable force that defeated the superpowers of that time.

"Those who disbelieve from among the people of the Scripture (Jews and Christians) and among Al-Mushrikn, were not going to leave (their disbelief) until there came to them clear evidence.
A Messenger (Muhammad (Peace be upon him)) from Allh, reciting (the Qur'n) purified pages [purified from Al-Btil (falsehood, etc.)]. Containing correct and straight laws from Allh.
And the people of the Scripture (Jews and Christians) differed not until after there came to them clear evidence. (i.e. Prophet Muhammad (Peace be upon him) and whatever was revealed to him).
And they were commanded not, but that they should worship Allh, and worship none but Him Alone (abstaining from ascribing partners to Him), and perform As-Salt (Iqmat-as-Salt) and give Zakt: and that is the right religion. Verily, those who disbelieve (in the religion of Islm, the Qur'n and Prophet Muhammad (Peace be upon him)) from among the people of the
Scripture (Jews and Christians) and Al-Mushrikn will abide in the Fire of Hell. They are the worst of creatures. Verily, those who believe [in the Oneness of Allh, and in His Messenger Muhammad (Peace be upon him)) including all obligations ordered by Islm] and do righteous good deeds, they are the best of creatures."
