(ʿAbd Allah b. ʿUmar (ra)) said, ”My father ʿUmar b. al-Khattab told me that Allah’s Messenger (saw) said, ‘Islam means that you testify that there is no god but Allah and that Muhammad (saw) is the messenger of Allah, and you establish prayer, pay zakāt, observe the fast of Ramadan, and perform the Hajj to the house (Kaʿba) if you have the means.’” (Muslim, al-Iman, 1)
According to Ibn ʿUmar (ra), the Messenger of Allah (saw) said, “Islam is based on five (principles): Testifying that there is no god but Allah and Muhammad is the Messenger of Allah, (fard/compulsory) prayer, paying zakāt, performing the Hajj (Pilgrimage to Mecca), and the fast of Ramadan.” (al-Bukhari, al-Iman, 2)
ʿUbada b. al-Samit (ra) informed us that the Messenger of Allah (saw) said, “Allah will make whoever says the following enter Paradise through whichever of its eight doors he would like: ‘There is no god but Allah. He is One and has no associate and Muhammad is his servant and His messenger. Jesus is the servant of Allah and the son of his mother and he (Jesus) is His word which He communicated to Maryam and is a spirit from Him. Paradise is a fact and Hell is a fact. Allah will make him enter from either of the all eight gates of Heaven He wishes’” (Muslim, al-Iman, 46)
Anas b. Malik (ra) reported that when Muʿadh (ra) was riding behind the Messenger of Allah on his mount, the Prophet (saw) said, “O Muʿadh bin Jabal!” Muʿadh replied, “At your service, O Messenger of Allah!” Again the Prophet (saw) said, “O Muʿadh!” Muʿadh said three times, “At your service, O Messenger of Allah!” The Prophet (saw) said, “Whoever testifies sincerely from his heart that there is no god but Allah and Muhammad is His Messenger, Allah will save him from Hell fire.” (al-Bukhari, al-ʿIlm, 49)
