Imam Jafar ibne Muhammad al-Sadiq (a.s.) said: ‘You (Shias) have looked where Allah ordered you to look and you have selected those whom Allah ordered you to select. People have gone here and there (in deviation) but you have gone to Muhammad (s.a.w.a.). You are on the right, shining path then help us by living piously. When Allah introduces knowledge of this affair (Wilayat of Ahle Bait a.s.) to any of you, then he must introduce it to the people…’
