Kindly help me verify if it is a sin to write Qur’anic verses on a black board using charcoal, wash off the written and then drink the water. I need an answer, as this is quite a common practice in my part of the world.
Some scholars say that this is permissible as it is a form of treatment through the Quran. Other scholars say that this is not permissible as it is an innovation and was not done by the Prophet salla Allahu alaihi wa sallam.
Therefore, it appears to me that one should not use such a method unless he tried everything else and nothing worked. However, one should make sure that this is not harmful for his health.
