SHAFAQNA (Shia International News Association) – Imam Sadiq (AS) always used to advise that every person must save for future so that in an emergency or if there is a need for money, a person would not go to others. One of the companions of Imam (AS) said: One day I was consulting my master, Imam Sadiq (AS) and told him: I have a land and someone wishes to buy it for a suitable price. Imam (AS) said: Do you know whoever sells his/her property, that asset will be wasted. I replied: I will sell it for a good price and intend to buy a larger land. Imam Sadiq (AS) said: In this case, it is alright to do so .
