Muslim also recorded that Mu'adh Ibn Jabal reported that the Messenger said: "What is due to God from His servants is that they worship Him, ascribe to Him no partner; and what is due to God's servants from Him is that He will not punish anyone that does not ascribe to Him a partner." Al-Bukhari, in his Sahih, recorded that Abu Hurayrah reported that the Messenger said to a questioner: The Iman (faith) is to believe in God, His Angels, His meeting, His Messengers, and to believe in the resurrection.
He said also to the questioner: Islam is to worship God, ascribing to Him no partner; to offer the prescribed prayers; to pay the prescribed charity, and to fast the month of Ramadan. Muslim recorded, in his Sahih, that 'Omar reported that the Messenger said to a questioner: "Islam is to testify that there is no God but the Almighty and that Muhammad is the Messenger of God; to offer the prescribed prayer; pay the regular charity; fast the month of Ramadhan, and visit the Ka'bah.
The same questioner asked the Prophet to inform him about Iman. The Prophet said to him: To believe in God, His Angels, His Book, His Messengers, the Day of Judgments, and to believe in: "Qadar," pleasant and unpleasant.
These authentic hadiths, plus many other reliable hadiths which I did not quote, agree with the Qur'an and indicate that whoever believes in God, His Angels, His scriptures, His Messengers, the Hereafter, worships God alone by offering the prescribed prayer, fasts the month of Ramadan, pays zakat, and performs the pilgrimage if he has the financial and physical ability, will be considered a Muslim in good standing.
There is no real difference between the Shiites and Sunnites concerning articles of the Faith of Islam. There is a disagreement between the two schools in two areas. 1. The Caliphate. 2. The Islamic rule when there is no clear Qur'anic statement, nor is there a hadith upon which Muslim schools have agreed. The disagreement about the caliphate should not be a source of division between the two schools. Muslims agree that the Messenger did not appoint Abu Bakr as the first Caliph.
They agree that his caliphate came through election. Election implies choice and freedom, and that every Muslim has the right to elect or not elect the nominee. Whoever refuses to elect him does not oppose God or His Messenger because neither God nor His Messenger appointed the nominee. Election, by its nature, does not compel any Muslim to elect a specific nominee.
