Question 3:Why we need the last prophet,the prophet Muhammad,and the last Holy Book,The Holy Quran?
Answer:We needed a last prophet,which is Muhammad,because the Divine message amny other prophets brought has been altered and misunderstood.We need a last book because The Holy Quran is only book that has not been altered and will not and cannot be altered.as milionns of Muslims know it by heart,whereas other holy books have been altered.If all copies of the Quran(which Allah forbid)were burnt,the very next moment the Quran would spring to live again from the milion who know it by heart.So you can see,there is no chance Quran ,being lost or altered
