SHAFAQNA – Ali ibn Mahziar narrated: I wrote a letter to Imam Baqir (AS) and complained to him about repeated occurrence of earthquakes in Ahvaz and asked: Should I relocate from there? Imam Baqir (AS) replied: Do not relocate from there, but fast on Wednesday, Thursday, and Friday and perform ablution (Qosl) and wear clean clothes, then come out on Friday and request from God to remove it (the earthquake) from you. Ali ibn Mahziar said: We did as Imam (AS) said until the earthquake calmed down .
