The believer is pure all the time and Janabah is an abstract concept

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. Yes, it is permissible for someone who is Junub (in a state of major ritual impurity), whether man or woman, to touch different things like clothes, plates, pots, etc before taking Ghusl (ritual bath). A Junub person is not Najis and so nothing is defiled by their touch. This is supported by the authentic Hadith reported on the authority of Abu Hurayrah (may Allah be pleased with him), who said: “The Prophet (peace be upon him) once met him on one of the paths of Madinah while he was Junub (in a state of major ritual impurity), so he slipped away to take a bath. (Part No. 5; Page No. 319) The Prophet of Allah (peace be upon him) searched for him and when he came, he asked him, ‘Where have you been, O Abu Hurayrah?’ Abu Hurayrah replied, ‘O Messenger of Allah, you met me when I was Junub, so I disliked sitting in your company before taking a bath.’ The Messenger of Allah (peace be upon him) said, ‘Subhan Allah (Glorified be Allah)! A believer never becomes Najis (impure).’” May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
