A man asked who is the best person and the Prophet Mohammed (SAW) said that it is the person who is sincere and someone who has a clean heart.
The prophet was asked about the clean heart and he responded by saying that, such a heart belongs to a person who does not commit sins, loves justice and someone who does not envy anyone.
Not being envious includes not being jealous of someone’s good fortune.
From these two Hadith of the prophet it shows that both things are related to the heart. Someone can talk sincerely with a sincere heart. So, if someone has this kind of heart, then that person has no obstacle in attaining paradise.
