Dr. `Abdel-Fattah Idrees, professor of Comparative Jurisprudence at Al-Azhar University, states the following: “The Prophet (peace and blessings be upon him) prohibited having belief in inanimate things as bringing any harm or benefit. It is reported that the Prophet (peace and blessings be upon him) says: “He who hangs an amulet or tamimah, Allah will deprive him of His Infinite Care, and he who believes that amulets have a certain effect on him has committed disbelief.”
Thus, such birthstones bring neither benefit nor harm because they are mere precious stones. Indeed, it is a real act of disbelief Kufr to think of such stones as having any ability to bring benefit or harm.”
In the light of the above fatwa, it’s clear that every Muslim is urged to have unswerving belief in Almighty Allah as the Absolute Power that controls everything, and nothing escapes Allah’s Sight, He is the Omnipotent and All-Knowing!
