7 - Narrated to us my father (r.a.): Narrated to us Saad bin Abdullah from Ahmad bin Abi Abdullah from his father from Ibne Abi Umair from Muhammad bin Abdur Rahman bin Abi Laili from his father from Abi Abdullah as-Sadiq 
– in a lengthy tradition – at the end of which he said:
“How can be guided one who has no insight? And how can one have insight without having the fear (of Allah)? Follow the statement of the Messenger of Allah (S) and confess to that which is revealed upon him by Allah, the Mighty and Sublime. And follow the signs of guidance. Indeed it is a sign of trustworthiness and piety. You should know that if someone denies the Messengership of Isa and believes in the Prophethood of all other messengers he is not a believer. Seek the path of Allah with the help of the minarets of guidance. Remain attached to that which is behind the veil so that the affairs of your religion become perfect and believe in Allah, your Lord.”
