each of them as harmful to you as all the terrors and afflictions of this world, and each of them regarding you with greed, anger and hatred. Your firm weapon, shield and citadel against all of them is none other than the brotherhood of Islam. So realize just how contrary to conscience and to the interests of Islam it is to shake the citadel of Islam on account of petty hostilities and other pretexts! Know this, and come to your senses!
According to a noble Hadith of the Prophet (PBUH), noxious and awesome persons like Sufyan and the Dajjal will come to rule over the godless at the end of time, and exploiting the greed, discord and hatred amongst the Muslims and mankind, they will need only a small force to reduce humanity to anarchy and the vast world of Islam to slavery.
O people of faith! If you do not wish to enter a humiliating condition of slavery, come to your senses and enter and take refuge in the citadel of:
to defend yourselves against those oppressors who would exploit your differences! Otherwise you will be able neither to protect your lives nor to defend your rights. It is evident that if two champions are wrestling with each other, even a child can beat them.
