Those who follow Quran and Ahl albayat ie Imams (عليه السلام) from the progeny of the prophet remain steadfast with truth. I admire your words in the light of hadith Thqalyn and verses of the quran praising Ahl alabayt (عليه السلام).
Actually Imams are the meezan (balance), so you must also look at the historical facts , how many of them defected in Siffin? Even the Khawarij came out from Imam Ali's (عليه السلام) camp.
How many defected Imam Hassan (عليه السلام)?
The companions, who remained steadfast on sirat e mustaqeem, are the light of our eyes. Who else is the Sirat except the Imams!
