Is it permissible to throw bags with brand names on them into the trash, or must they be burned for fear of disbelief (kufr)? And what if they contain Hadith or Quranic verses?

What bears the name of Allah must be preserved and respected. It is not permissible to degrade it by placing it in the trash. These papers can be disposed of by effacing or erasing the name of Allah through washing, tearing, burying in a pure place, or burning when necessary, in order to avoid degradation.
