Hazrat Wa’il bin Dawood narrates that I heard Hasan Basri describing that there was a man among us who saw in a dream that a caller announced from the sky: O people! Take up your weapons for your fear and anxiety. Then the people intended to do so and took up their weapons. Until a man came who did not even have a staff. Then a caller announced from the sky: These are not the weapons for your anxiety. So a person from among the people of the earth asked: What are the weapons for our anxiety? He said: These are the words: Allah is free from all defects, and all praise is for Allah, and there is no deity except Allah, and Allah is the Greatest.
