Ruling on Salaah al-Uns that is offered on the day of burying a deceased?

Question 464: What is the authenticity of Al-Uns Salaah (prayer)? It is performed after Maghrib (Sunset Prayer) on the day of burying the deceased. Did the Prophet (peace be upon him) perform such Salaah, and how should it be performed?

Answer: Al-Uns Salaah is one of the innovated Salaah. It is an impermissible Bidd`ah (innovation in religion) because acts of worship are based on divine texts. None should worship Allaah except through His legislation. It was authentically reported from the Prophet (peace be upon him) that he said: Whoever introduces something into this affair of ours that is not of it, it will be more here.
