According to the traditions...
According to the traditions, worship during the days of tyrannical government is more rewarding for the believers than worship during the time of the just government, though this fact should not prevent the believers from praying to Allah for the manifestation of the Kingdom of Justice on earth by Imam al-Mahdi (PBUH).1 The rights and virtues of Imam Ali and other Imams The sermon of Ghadir Khum confirms the following rights and virtues of Imam Ali (PBUH) and the Imams after him: 1- Allah has decreed absolute authority for them over the believers, and thus, just like the Prophet (PBUH&HF), all their commands must be obeyed unconditionally.
2- Like the Prophet (PBUH&HF), they have priority over people, and they have more rights over the believers 1 cf. al-Kafi, vol. 1, p. 333, Hadith 2, also Hadith 1; Bihar al-Anwar, vol. 52, p. 127, Hadith 20, also p. 145, Hadith 67. Another related tradition can be found at: al-Ikhtisas, p. 20, Hadith; Bihar al-Anwar, vol. 52, p. 144, Hadith 62. than what they have over their own souls. They should be preferred over others (in position, sayings, ideas, commands, etc.) for Allah has preferred them.
3- Allah has made them the leaders of the believers and the medium of divine guidance after the Prophet (PBUH&HF). They guide people towards the pleasure of Allah, keep them from His disobedience and His wrath, and lead them to Paradise. 4- Allah has made them the guardians of the faithful, who protect their close adherents from evil and misguidance. 5- They are the پgStraight Pathپh of Allah, whom people are ordered to follow. 6- They have all the knowledge of the Prophet (PBUH&HF).
Allah has placed the knowledge of everything in them. They are the inheritors of all branches of knowledge. Particularly, they possess the complete knowledge of religion. They are authorized to expound the religion and explain its commandments and prohibitions. 7- Allah has authorized them to interpret the Holy Quran and to explain its meaning after the Prophet (PBUH&HF). No one knows its interpretations, its hidden warnings, and its mysteries except through them.
They guide people to the truth of the Quran and call them to it. 8- They are the executors of the will of the Prophet (PBUH&HF) and the deputies of his affairs (Wasi). Imam Ali (PBUH) was the greatest in virtue and rank among the deputies of all the prophets (most of whom were prophets themselves) just as the Prophet (PBUH&HF) was the greatest among all prophets (PBUT).
