(The same previous series of relaters)… from Sulaiman that Dawoud bin Kuthair ar-Raqqi said: When I was before Abu Abdullah (a), I said to him: Allah may make me your sacrifice. Regarding the Holy saying of Allah, "I am All-forgiving to him who repented, believed, and did righteous acts then followed the right guidance, (20:82)" what is that right guidance, which comes after repentance, faith, and the righteous acts? He (a) said: (This right guidance is) the acknowledgement of the Imams-one after the other.
