Is it true that a Muslim's prayer is not accepted for forty days if he calls another Muslim a "pig"?

A Muslim should discipline their tongue from every ugly word. And whoever utters an ugly word that combines lies and offense should repent to Allah and seek forgiveness from the one they wronged. It is not true that one who utters an ugly word will not have their prayers accepted for forty days. This punishment is specific to the wine-drinker and the one who approaches a soothsayer and believes them.
