Ayat 44 Of Surat Ma'eda Considered.

In Ayat 44 of Surat Ma'eda (5:44) of the Holy Qur'an, Allah Subhanahu Wa Ta'ala says, ''WE SENT DOWN THE TORAH, WHEREIN IS LIGHT AND GUIDANCE; THEREBY THE PROPHETS, THOSE WHO ARE MUSLIMS, JUDGE FOR THOSE WHO ARE JEWS''.
The Shari'a of Prophet Muhammad, may Allah bless him and grant him peace, has established the Shari'a of preceding generations. His Law is its root, as he was sent ''TO ALL PEOPLE'' (Quran-34:28), while this belonged to no other prophet. ''PEOPLE'' extend from Adam to the last human being, and among them there have been Laws, so they are the Laws of Muhammad in the hands of his Deputies. For he is sent ''TO ALL PEOPLE'', so all the Messengers are his deputies, without doubt, Sallallahu alaihi Wasallam.
Thus when he came, he came with someting great that comprised everything which was scattered among his deputies and something in addition. Hence God gave him the Mother Of The Book, which comprised all the scriptures and books.
