A : It is permissible to write the Basmalah on invitations and other letters, because of what has been related from the Prophet (peace be upon him) that he said: Any important issue that is not started by Basmalah (in the name of Allah) will be deprived of blessing. The Prophet (may Allah's Peace and Blessings be upon him) also used to begin his letters by mentioning the name of Allah. It is not permissible for anyone who receives a letter in which Allah is mentioned or an Ayah of the Qur'an is quoted to throw it into the garbage or put it in any undesirable place. The same applies to newspapers and other similar papers: it is not permitted to mishandle or throw them in the garbage or to use them to wrap food or other things, because the name of Allah is mentioned in them. The sin is on the person who does this, not on the one who writes it.
