Answer:
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad 
is His slave and messenger.
It is an obligation to preserve any object that has the Name of Allaah or a name of a prophet written on it from being degraded. It is forbidden to throw it in a dirty place. If someone sees such an object at a dirty place, it is forbidden for him to leave it there if he can take it out.
Some scholars stated that anyone who leaves an object that has the Name of Allaah written on it at a filthy place goes out of the fold of Islam if he knows that it has on it what must be venerated.
Shaykh Ad-Dardeer (from the Maaliki School of jurisprudence) said in Ash-Sharh Al-Kabeer regarding the statement of Khaleel, 'like throwing a Mus-haf in a dirty place': “Even if the dirt is something pure like spit, or smearing it with it. What is meant by Mus-haf is anything on which the Quran is written, even if it is only one word thereof. The same applies to leaving it in that dirty place, i.e. not taking it out if one finds it there because leaving it there is like putting it there in the first place. Yet putting it there is a physical act and leaving it is a moral one. What applies to the Quran applies also to the Beautiful Names of Allaah and the names of the Prophets, as well as the Hadeeth as it is apparent....” [End of quote]
This is so if the person knows that the Name of Allah is written on the thrown paper; but if one does not know, he is not obliged to search and inspect.
Allaah Knows best.
