Do not the Ahle Sunnat...
Do not the Ahle Sunnat, consider it necessary and compulsory to recognize Abu Bakr and Umar despite their weakness? Zurarah said: Yes, they do. Then the Hazrat said: Do you imagine that Allah has put the recognition of the two in their hearts? No, by Allah, none but the devil has put it in their hearts and, by Allah, none but Allah has put our recognition in the hearts of the believers.
He has also narrated with reliable chains of narrators from Jabir who says that he heard Imam Baqir (a.s.) saying: No one either knows or worships Allah but the one who knows Allah and knows the Imam of his time from us Ahlul Bayt (a.s.). And the person who does not recognize Allah and Imam of his time from we Ahlul Bayt (a.s.), of course knows [believes in] others than Allah and worships other than Allah and, by Allah, he goes astray due to ignorance and misguidance.
Also he has narrated with reliable chains of narrators from Imam Sadiq (a.s.) that the Hazrat said: You people cannot be righteous and good until you know the Imam and you cannot get the required knowledge unless you do not testify and you did not testify until you obey and follow the four things mentioned in the verse. The four things which are true are repentance, faith, good deeds and the guidance gained through the guardianship (Wilayat) and obedience of the Imams.
Then he added….their beginning is not improved but through the end of Imamate and they cannot benefit but through Wilayat and those who do not believe in the said three things are wayward. Verily Allah does not accept but good deeds but then He does not accept the good deeds but with the completion and fulfilment of the conditions mentioned in the verse.
Allah only accepts from those who guard (against evil). (Sura Maida 5:27) So the one who fears Allah regarding the matters commanded by Allah meets Allah with Faith in the things brought by Muhammad (S). Alas, alas, how distant this group is from Grace.
