Nabi (Sallallaahu ‘Alayhi Wasallam) said,
“Soon there will be such fitan (trials) that in them a person will be Muslim in the morning and a kaafir by evening, except for that person whom ALLAH Ta‘ala saves through ‘Ilm (Knowledge).” (Daarimee)
Explanation
What can it mean to keep alive through ‘Ilm (Knowledge) be that, the person knows the boundaries of kufr and Eemaan. He knows what makes a person Muslim and what makes him kaafir.
As advised in the above Hadeeth Mubaarak, to learn the ‘Ilm-e-Deen from ‘Ulamaa-e-Haqque and to make ‘Amal upon it is the only way to safeguard one’s Deen in this age of Eemaan ravaging fitan.

رَبَّنَا لَا تُزِغْ قُلُوبَنَا بَعْدَ إِذْ هَدَيْتَنَا وَهَبْ لَنَا مِن لَّدُنكَ رَحْمَةً ۚ إِنَّكَ أَنتَ الْوَهَّابُ •
Our RABB, Do not cause our hearts to stray after You have Guided us. Grant us Your Mercy (O Turner of Hearts, keep our hearts steadfast on Deen) for verily You are the Great Giver (of all things)…Aameen
