The word "tajweed" means to improve, make better. 1] Tajweed of the Holy Qur'an is the knowledge and application of the rules of recitation so the reading of the Qur'an is as the Prophet Mohammed peace and blesings be upon him, recited. 2] Hadith is the collection of the Prophet Muhammad’s peace be upon him statements . There are 7 recitations all of them were listened from Prophet Mouhammad (pbuh) by succession. The different between them come from the way Gabriel recited to Prophet Mohammad (pbun), Gabriel recited the 7 recitations to Prophet Mouhammad (pbuh) and the Prophet Mohammad then recite them to his companions . The different is in the pronunciation of some words or in writting some of them but that never affect on the meaning of any single word between all of the 7 recitation . so all of the recitations have the same meaning for all the words .
