First the Qu'ran says that Allah did sent the Torah, the Psalms, and the gospels:
We gave Moses the Book and followed him up with a succession of messengers," (Sura 2:87).
"We have sent thee inspiration, as We sent it to Noah and the Messengers after him: we sent inspiration to Abraham, Isma'il, Isaac, Jacob and the Tribes, to Jesus, Job, Jonah, Aaron, and solomon, and to David We gave the Psalms," (4:163).
"It is He Who sent down to thee (step by step), in truth, the Book, confirming what went before it; and He sent down the Law (of Moses) and the Gospel (of Jesus) before this, as a guide to mankind, and He sent down the criterion (of judgment between right and wrong)," (3:3).
Also, "And in their footsteps We sent Jesus the son of Mary, confirming the Law that had come before him: We sent him the Gospel: therein was guidance and light, and confirmation of the Law that had come before him: a guidance and an admonition to those who fear Allah," (5:46).
Now Muslims would say these things are true. But the Torah and gospels we have now are corrupted. Well let us see what the Qu'ran says about those Books being corrupted:
Rejected were the messengers before thee: with patience and constancy they bore their rejection and their wrongs, until Our aid did reach them: there is none that can alter the words (and decrees) of Allah. Already hast thou received some account of those messengers," (6:34).
"The word of thy Lord doth find its fulfillment in truth and in justice: None can change His words: for He is the one who heareth and knoweth all," (6:115).
For them are glad tidings, in the life of the present and in the Hereafter; no change can there be in the words of Allah. This is indeed the supreme felicity," (10:64).
Now, am I suppose to take every single verse here literally like you Muslims take every single verse in the Bible literally, or is there figurative language involved? If you are going to make arguments against these sayings, please do not use double standards as you normally do.
