I have a question regarding the recite of adhan & iqama.
After saying « ashadu ina Muhammadan rasoul Allah » should I say « allahuma salle aala sayedna Mohamad wa ali Muhammad » as I’m citing his name ? Same for imam Ali as should I say aalayhi assalam ?

Also I’m a student in Europe and my only way to pray Salat al jumaa is with our sunni brothers, is it allowed and is my prayer accepted ? I try to take my turbah with me

You should send salawat after both names and you can pray yes but repeat your salah afterwards ( Zuhur only)
