Sayyiduna Abu Hurairah (may Allah be pleased with him) reports: The Prophet (peace and blessings be upon him) came to us and said: "Take your shield." We said: O Messenger of Allah! Has an enemy come? He (peace be upon him) said: "Take your shield from Hell. Recite these words: ' «سُبْحَانَ اللّٰهِ وَالْحَمْدُ لِلّٰهِ وَلَا إِلٰهَ إِلَّا اللّٰهُ وَاللّٰهُ أَكْبَرُ وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللّٰهِ» '. These words will be saviors from the front and the back on the Day of Resurrection, and they will be good, lasting words."
