Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) says: On the day of the Trench, we said: O Messenger of Allah! Is there any dhikr (remembrance) that we can say (to relieve our anxiety), our hearts have reached our mouths? The Prophet (peace and blessings of Allah be upon him) said: “Yes, say: O Allah! Conceal our faults and grant us security from our fears.” Then Allah, the Exalted, sent a (violent and fierce) wind upon the enemies and defeated them through the wind.
