Bismillah,

Imam Musa ibn Jafar narrated from his forefathers, that prophet (sallalahu alaihi wa ala alihi wa sallam) said:

أنا آمن لأصحابي- فإذا قبضت دنا من أصحابي ما يوعدون- و أصحابي أمنة لأمتي- فإذا قبض أصحابي دنا من أمتي ما يوعدون- و لا يزال هذا الدين ظاهرا على الأديان كلها- ما دام فيكم من قد رآني من رآني

I am protection (amanah) for my companions, and when I will go,  (predestination) would get closer to my companions. AND MY COMPANIONS ARE PROTECTION FOR MY NATION, AND IF THEY WILL GO, (PREDESTINATION) WOULD GET CLOSER TO MY NATION. THIS RELIGION WOULD BE DOMINANT OVER ALL OTHER RELIGIONS, UNTILL BETWEEN YOU WOULD BE PEOPLE WHICH SEEN THOSE WHO SEEN ME.

Discussion: Just have a look, that prophet (sallalahu alaihi wa ala alihi wa sallam) didn’t bind protection and victory of Islamic nation with the presence of masoom Imam! He linked it to presence of tabioon.
