Q: What is the ruling on pronouncing the Adhan (call to prayer) and Iqamah (call to start prayer) inside the grave of the dead when burying them?
A: There is no doubt that this is a Bid`ah (innovation in religion) which was not prescribed by Allah, for such an act has not been reported from the Messenger of Allah (peace be upon him) or any of his Sahabah (Companions of the Prophet) (may Allah be pleased with them). All good is attained by emulating their practices and following their path as Allah (Glorified be He) states:
And the foremost to embrace Islâm of the Muhâjirûn (those who migrated from Makkah to AlMadinah) and the Ansâr (the citizens of AlMadinah who helped and gave aid to the Muhâjirûn) and also those who followed them exactly (in Faith). Allâh is wellpleased with them as they are wellpleased with Him.
Whoever introduces something into this affair of ours that is not of it, it is to be rejected,
Whoever performs an act which is not of our affair, i.e. religion, it is to be rejected.
The most evil affairs are their novelties; and every innovation is error.
May peace and blessings be upon our Prophet Muhammad, his family, and Companions!
