A Junub reciting the Qur'an without touching the Mus-haf
A:
The Jumhur (dominant majority of scholars) are of the opinion that
it is not permissible for the Muslims to read the Qur’an while they are Junub (in a state of post-sexual ritual impurity), even if they intend to recite it from memory, without touching the Mus-haf (copy of the Qur’an).
Ahmad and the Compilers of Sunan (Hadith compilations classified by jurisprudential themes)
reported on the authority of
`Aly (may Allah be please with him) that he said:
Nothing prevented the Prophet (peace be upon him) from reciting the Qur’an, except Janabah (major ritual impurity related to sexual discharge).
(Al-Hafizh ibn Hajar (Part No. 4; Page No. 108) ranked its Isnad (chain of narrators) as good) If they cannot find water or are unable to use it due to illness, they are permitted to perform Tayammum.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
