Does the saying of the Prophet (peace be upon him), "Two men who do not speak to each other will not enter Paradise," apply to me because of a misunderstanding that occurred with a person I have not seen since then?

Abandonment (hajr) between Muslims is not permissible for more than three nights if it is intentional. However, if separation occurs unintentionally and a meeting is not facilitated, it is not considered the forbidden abandonment, and one is not required to seek out the other except for kin. A Muslim should be keen on fostering affection, kindness, exercising good judgment, and forgiveness. There are established hadiths prohibiting estrangement and a Muslim abandoning his brother.
