All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
There is no doubt that it is not Kufr or Shirk to simply hang up frames in which the Name of Allah is written next to the name of the Prophet Muhammad or to put such frames next to the television in which programs that include Islamic prohibitions are shown.
It is obvious that your question stems from the excessive obsession (whispers) which you are affected with; we ask Allah to cure you from it.
The cure to this is to totally ignore these whispers, stop busying yourself with them, refrain from giving in to them, stop asking questions about them, and to supplicate Allah to cure you from them.
It is also good to consult with psychiatrists, to treat your Obsessive-Compulsive Disorder.
Asking too many questions and detailing issues will not cure you from whispers. Rather, this will make you even more obsessed and confused.
It is true that some contemporary scholars –such as the Standing Committee, Ibn 'Uthaymeen and others – have forbidden joining the name of Allah and the name of Muhammad in frames as they consider this to be an exaggeration, but they never said that this is Kufr.
However, the view that we adopt is that this issue cannot be categorized as absolutely forbidden, because merely joining the two names is something which exists in many religious texts [in the Quran and the Sunnah]
Also, hanging up the verses or Athkaar (mention of Allah) in places of forbidden entertainment is regarded as a moral insult to it according Ibn ‘Uthaymeen as he said:
"However, some gatherings –or many of them – where verses are written (in the place of gathering) may involve idol talk, and it may even include forbidden statements, or forbidden songs, and this is a clear moral despise to the Quran." [End of quote]
However, he did not consider this action to be Kufr or Shirk.
Allah knows best.
