3893. It was narrated from 'Amr bin Shu'aib, from his father, from his grandfather that the Messenger of Allāh ﷺ used to teach them words to say in the event of fear: "A'ūdhu bikalimātillāhit-tāmmati min ghadabihi wa sharri 'ibādihi, wa min hamazātish-shayātini wa an yahdurūn (I seek refuge in the Perfect Words of Allāh from His Wrath and the evil of His slaves and from the suggestions of the devils and from their presence)." 'Abdullāh bin 'Amr used to teach it to those in his household who reached puberty, and for those who had not reached puberty he would write it down and hang it on them. (Da'if)
