SHAFAQNA – It is narrated from Imam Sadeq (AS) by the great Shia scholar Sheikh Toosi (RA) from authentic references that: At the time of earthquake, recite the following Dua: O’ (God) who keeps the skies and the earth from collapsing (falling down), and if they collapse, no one except God can hold them. God is kind and forgiving; send greetings (Salawat) to Mohammad (PBUH) and his family, and prevent (hold back) badness from us, because (only) God is capable of doing anything. Imam Sadeq (AS) continued by saying: Whoever recites this Dua at the time of sleeping, the house will not fall on him/her (God willing) .
