Respect for Deeni Literature

Q: 

1. Is it permissible to dispose of something with the name of Allah Ta'ala written inside of it, if the writing is covered? 

For example, a copy has random pages where the name of Allah Ta'ala is written, but these writings are covered by other pages and covers of the copy. 

2. If not, then is one required to check every copy and mark over them so it cannot be seen? 

3. What other writings does one have to cut off (or just cover) before disposing?

Q: I have Islamic cds and cassettes. Am I allowed to recycle them?

Q: It's seen in many places that kitaabs, Islamic literature and even Quraans are placed terribly in Darul Ihsaan boxes so if after a person puts posters explaining that the kitaabs should be placed nicely the people still don't listen than should the boxes be removed?

Q: How do I discard a broken glass with a Quranic dua printed over it?

Q: Is it permissible to sell a children's blanket which will have some decorations, a name on it (e.g. Zain) and with it will be "Allahuma bismika Amooto wa Ahyaa"?

Q: Just like we can't place our feet above the Quran Kareem, does the same apply to Deeni books such as hadeeth and tafseer?

Q: Once, a hadeeth kitaab was sent to the copy shop. The workers there were not handling the kitaab with care for which some students teased the one who owned the kitaab. Is this tantamount to kufr? I believe that they were laughing at the way the workers were handling the kitaab and not looking down on the kitaab itself.

Q: Is it okay to write Allah’s name with a small ‘a’ with no intention of disrespect?
