The sources of divine legislation for Muslims are: The Holy Quran and the "Sunnah" of the Prophet Mohammed (peace and blessings be upon him), that includes the hadiths of the Prophet Mohammed (peace and blessings be upon him), by word nor deed and his honorable biography. He inherited the Muslims from the Prophet Mohammed (peace and blessings be upon him), the noble "Sunnah", which is an explanation and a clear indication of the Holy Quran. Allah has revealed the Qur'an to the Prophet Mohammed (peace and blessings be upon him), and the Prophet clear and explained it to all the people. But the prophetic "Sunnah", especially the "Haadeeths", was exposed during the period of the Umayyad rule to sedition and the emergence of fraud and the situation and beyond to be distorted by corrupters. The Umayyad decrees have spent large sums of money so that the corrupters may put the weak of the souls in the hadiths to praise them, thus making the entry of a large number of false hadiths mixed with the correct "Hadeeth" from (Al- Hadeeth Al-mawdoo3). However, our righteous scholars put transmitting the prophetic tradition, authentic "hadeeth" and the atheists and divided the atheists to the right and the good and the weak and strong and classified the men of the modern and praise and ways to transfer to the other nothing remained in the "hadeeth" only they made it clear and classified it according to the type of "hadeeth". Allah rewarded them well for what they did to show the more authentic Hadeeth than others, The Quran is authentic in all ages since the revelation of God until this age, it is authentic and the terms of the authentic Hadeeth must be so, but we have reached a few of these impossible conditions that require hadeeth authentic.
