Scriptures as plural refers to what?

Messengers is also plural! So Jesus Christ was a messengers also, so why not read the scripture containg the words he said?
002.285 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
