All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
Imaam Muslim narrated in his Saheeh that the Prophet said, “The deeds of people are presented to Allaah on every Monday and Thursday. Allaah forgives every Muslim who does not associate any partner to Allaah, except a person who is in dissension with his Muslim brother; it will be said, 'Leave them until they reconcile, leave them until they reconcile.'”
This hadeeth does not apply to you and your friend because you did not abandon each other; rather, you now live in different countries far away from each other. However, if you meet him in the future, then you should treat him well, just like any other Muslim.
Allaah knows best.
