Q: If a Muslim has doubts that some of his clothes are not pure without discerning (Part No. 6; Page No. 68) any traces of Najasah (ritual impurity) on his garment, what is the ruling in this regard?
Likewise, if the Mu'adhin (caller to Prayer) was Junub (in a state of major ritual impurity) at the time of Fajr (dawn) Adhan, should he go to the Masjid (mosque) to perform the Adhan, then return home to make Ghusl (ritual bath)?
once he has doubts regarding the purification of part of his clothes, then he should stick to the basic principle which is Taharah (ritual purification) and what is certain cannot be altered by something doubtful.
the Junub should not stay in a Masjid to announce Adhan or anything else, for the Prophet (peace be upon him) said,
I do not make the Masjid lawful for a menstruating woman or for a person who is Junub.
With regard to the Adhan, it is not a condition for its validity that the Mu`adhin be pure; it is preferable to declare the Adhan while being free from both major and minor ritual impurities.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
