:Imam Sadiq’s (PBUH) warnings
I swear to God, you will break undoubtedly such as shattering of a glass but glass can be recycled (by melting and reproducing). I swear to God you will break like pottery, very truly it does not return to original condition
I swear to God you will be screened and distinguished from each other undoubtedly and you will be selected until a few of you remain
