The young man may not leave his jogging session, he may skip salah with jamaath.

subhanallah i do not want to miss the jamath...as for jogging i can simply change the times
but as for classes, when ic ome back its time for maghrib and i have to head straight to the mosque which is a concern - as im smelly
just want to know if its impermissible

A similar experience. young boys wear T-shirts with slogans, they ask us, "can we come to the masjid with this dress", a tricky situation, if you send them back for change of dress, they may do it now, but on some other ocasion they may not turn up of salah.

funny you should mention that. as i sometimes come back from training with t shirts with pictures on, i simply turn them inside out
