Belief in the Revealed Books

The Prophet (may Allah's peace and blessings be upon him) warned his Ummah not to get deceived by what the People of the Book report in their books. The Jews, during the Prophet's lifetime, used to read the Torah in Hebrew, the language of the Jews, and expound on it in Arabic. So, the Prophet (may Allah's peace and blessings be upon him) said: Neither believe nor disbelieve the People of the Book. This applies to things that are not known to be true or false. In fact, Allah Almighty commanded us to believe in the Qur’an revealed to us and the Book revealed to them. But there is no way in which we can know whether what they relate to us from these books is true or false, unless our Shariah clarifies whether it is true or false. Hence, we should stop, neither believing them, lest we may become their partners in what they distorted, nor disbelieving them, lest their statement may be right, and thus we will be denying what we were commanded to believe in. And Allah Almighty commanded the Prophet (may Allah's peace and blessings be upon him) that we should say: {We believe in Allah and what has been sent down to us; and what was sent down to Abraham, Ishmael, Isaac, Jacob, and the descendants [of Jacob]; and what was given to Moses and Jesus; and what was given to the prophets from their Lord. We make no distinction between any of them, and to Him we have submitted.} [Surat al-Baqarah: 136]

The Companions (may Allah be pleased with them) were the most eager of people to follow the Messenger of Allah (may Allah’s peace and blessings be upon him) in every aspect. They would even walk in the same path that he used to walk in, sit in the same places he used to sit in and do everything they knew he used to do. This Hadīth is a proof of that, as Abu Bakr and ‘Umar visited a woman whom the Messenger of Allah (may Allah’s peace and blessings be upon him) used to visit. They visited her only because of this. When they arrived at her home, she began to weep. They said to her why are you weeping? Do you not know that what Allah, Glorified and Exalted be He, has prepared for His Messenger is better than this world? She replied: I do not weep because of that, but rather because the revelation has ceased. This is because when the Prophet (may Allah’s peace and blessings be upon him) passed away, the revelation stopped, as there is no revelation after him. That is why Allah perfected the Shariah before he passed away. Allah, the Almighty, says: {This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion} [Al-Mā‘idah: 3]. Upon hearing her words, Abu Bakr and ‘Umar started weeping as well because she reminded them of what they had forgotten.

Allah, Exalted and Glorified, increased the revelation that was sent down to the Messenger of Allah (may Allah's peace and blessings be upon him) before his death to complete the Shariah, up until the Messenger (may Allah's peace and blessings be upon him) died at a time when the revelation was most abundant.
