Polluted Tongue and Heart

 Imama Sadiq (as) says  “A man of Bani Israel recited Dua for three years invoking God to give him a son.  But when he realized that his Dua was not answered, said: O God! Am I far from You?  Don’t You hear my voice or You hear it but do not answer?   In his dream, he saw a man saying: You have been calling upon God with a polluted tongue and heart and false intention for three years.  You have to cleanse your tongue and heart with piety and correct your intention.  The man did so for a year and then God gave him a son.” Reference : Oddatud Daee
