Every age has a different challenge. When Nabi (sallallahu ‘alaihi wasallam) left this world then there was the challenge of those who reneged from Islam. Then in one age there existed the challenge of preserving the ahaadeeth of Rasulullah (sallallahu ‘alaihi wasallam). These challenges always existed throughout every era and will continue to surface in different ways till the Day of Qiyaamah. But there will always be the group who will stand for the truth. They will work hard to preserve Islam in the face of these challenges and clear the way for the rest of the Muslim Ummah.
