the holy qur'an says to prophet ibrahim (a.

the holy qur'an says to prophet ibrahim (a.), " i appoint you a leader", ibrahim said, " what about my descendants"? god said, " an unjust people cannot reach my promise". (2 :124) these five principles are called usul-ud-din which means articles of faith. Succession to the prophet Muhammad (p.) shi'a believe that someone should have been appointed by the prophet muhammad (p.) to lead the muslims to the right path. therefore, the prophet (p.) did not leave this world without such an appointment.

no wise leader would do so; every leader has someone to carry his message after him. therefore, in the case of the prophet (p.), according to shi'a, he appointed imam ali (a.) as his successor. it is impossible to say that the prophet (p.) ignored this important matter. in addition, it was not possible for muslims to ask the prophet (p.) about minor things but forget such an important matter while they used to read holy qur'an addressing the prophet muhammad (p.) explained this.

among them are the following reports. hadith-ul-manzila : when the prophet (p.) went to tabuk in the 9th year a.h., he left imam ali (a.) in madina and said " wouldn't you like to be to me as haroon (a.) was to moses (a.)?" sahih bukhari vol :5 p. 24, cairo. sahih muslim adds to this report the following phrase, " but there would be no prophet after me ". sahih muslim vol : 7 p. 120, cairo. the prophet muhammad (p.), in this report, appointed imam ali (a.) as moses (a.) appointed haroon (a.).

the holy qur'an defines the relationship between haroon (a.) and moses (a.) as follows : a). succession : the holy qur'an says, " moses says to his brother haroon, succeed me among my people and righteous and do not follow the way or mischievous people". (7 :142). b). help : the holy qur'an says, " amid appoint for me a helper from my family, haroon my brother ". (20 :29-30). c). consultant : the holy qur'an says, " and consult him in my affairs ". ( 20-32).

therefore, all of the mentioned in the holy qur'an should be for imam ali (a.) as it was for haroon. 2. hadith-ul-thaqalain : the prophet (p.) said, " o, people ! i am a human being, i am going to die and i leave two valuable things among you, one is the book of allah, in it you find guidance and light ". then said, " and my family (ahl-ul-bayt), i remind you, the ahl-ul-bayt three times". see sahih muslim vol :7 p. 121.

hadith-ul-ghadir : it is a place between mecca and madina in which the prophet (p.) gave a ceremony on 18th dhul hijjah 10th a.h.
