The order to believe in those original books came from ALLAH as its said in the Quran and also as said in the phrophet's saying
here is what the Quran said (three translation):
002.285
YUSUFALI: The Messenger believeth in what hath been revealed to him from his Lord, as do the men of faith. Each one (of them) believeth in Allah, His angels, His books, and His messengers. "We make no distinction (they say) between one and another of His messengers." And they say: "We hear, and we obey: (We seek) Thy forgiveness, our Lord, and to Thee is the end of all journeys."
PICKTHAL: The messenger believeth in that which hath been revealed unto him from his Lord and (so do) believers. Each one believeth in Allah and His angels and His scriptures and His messengers - We make no distinction between any of His messengers - and they say: We hear, and we obey. (Grant us) Thy forgiveness, our Lord. Unto Thee is the journeying.
SHAKIR: The messenger believes in what has been revealed to him from his Lord, and (so do) the believers; they all believe in Allah and His angels and His books and His messengers; We make no difference between any of His messengers; and they say: We hear and obey, our Lord! Thy forgiveness (do we crave), and to Thee is the eventual course.
and the hadith : in sahih bukhary
in the book of authentic sayings named Sahih bukhary in the chapter of belief (Faith)
Narrated By Abu Huraira : One day while the Prophet was sitting in the company of some people, (The angel) Gabriel came and asked, "What is faith?" Allah's Apostle replied, 'Faith is to believe in Allah, His angels, (the) meeting with Him, His Apostles, and to believe in Resurrection." Then he further asked, "What is Islam?" Allah's Apostle replied, "To worship Allah Alone and none else, to offer prayers perfectly to pay the compulsory charity (Zakat) and to observe fasts during the month of Ramadan." Then he further asked, "What is Ihsan (perfection)?" Allah's Apostle replied, "To worship Allah as if you see Him, and if you cannot achieve this state of devotion then you must consider that He is looking at you." Then he further asked, "When will the Hour be established?" Allah's Apostle replied, "The answerer has no better knowledge than the questioner. But I will inform you about its portents.
1. When a slave (lady) gives birth to her master.
2. When the shepherds of black camels start boasting and competing with others in the construction of higher buildings. And the Hour is one of five things which nobody knows except Allah.
The Prophet then recited: "Verily, with Allah (Alone) is the knowledge of the Hour..." (31. 34) Then that man (Gabriel) left and the Prophet asked his companions to call him back, but they could not see him. Then the Prophet said, "That was Gabriel who came to teach the people their religion." Abu 'Abdullah said: He (the Prophet) considered all that as a part of faith.
And I ask Allah Our Creator and Sustainer to guide every one to the straight path that leads to heavens and paradise
Amen
