Hadith on Dhikr: Your shield from Hellfire is remembrance of Allah

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Take up your shields.” They said, “O Messenger of Allah, is the enemy present?” The Prophet said, “No, rather your shields from the Hellfire are to declare the glory of Allah, the praise of Allah, there is no God but Allah, and Allah is the greatest. Verily, they will come on the Day of Resurrection as saviors and guardian angels, and they are ‘righteous deeds everlasting.’” (18:46)
