Shafaqna (International Shia News Agency) – The Grand Ayatollah Sistani answered some questions regarding holy names. According to Shafaqna the questions and answers are as follows:
Question: We usually receive wedding invitation cards, which have ‘In the Name of Allah’ written on them. What should we do with them, as we are not allowed to throw them in the sea and it is difficult to bury them? Can we give them to the places that gather paper to be recycled?
Answer: If you cannot bury them in the ground, you can give them to a recycling company.
Question: Other than throwing papers with the name of Allah and other personalities in water (which is technically not permissible according to the laws of the West to avoid pollution and other things) what can Muslims do? Are we permitted to recycle these things in government-sponsored programs?
Answer: If the papers are not mixed with najis things and throwing them into recycle bin is not considered disrespectful, there is no problem.
