,السلام علیکم و رحمة الله و بركاته During the Salat in Jamma3, if a man joins in the last raka3 he has caught the Jamma3. If someone comes and joins him and prays behind him for all 4 rakats, have they also caught the Jamma3, or must they have prayed with the 1st Imam? !بارك الله فيك وأكرمك أستاذ

Ustadh AbdulAziz al-Haqqan

They prayed in jama'ah yes.
