أحسن الله إليكم If the follower doesn't catch up in time with the imam because the imam leads so fast that he doesn't have time to say the wajibat of salah, should the follower repeat the raka' after the imam says tasleem or make sujood as-sahw after imam gives tasleem? جزاك الله خير

Ustadh AbdulAziz al-Haqqan
There are details, if the Imam is so fast that no one is able to say what is mandatory then you don't pray behind him. But, if you are slow then u need to hurry up instead and the salah is correct.
