Question:
I want to know: Who is the muhaajir (person who migrates) among the following? 1.The one who leave his/her own country and settles down somewhere else permanently? 2.The one who merely migrates for the sake of trade or business for a few days but does not permanently settle there?
Answer:
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.
Migration in the language of the Arabs refers to leaving the first place and going to another place and settling there. Based on this, the one who moves from one country to another with the intention of ending residence in the first place and settling in the second place has migrated.
Residing in a second place for a period of time in order to achieve a benefit with the intention of going back to the first place is not migration.
Migration could be for a worldly purpose, such as someone who migrates for trade, work, marriage, or other worldly purposes and settles in the country where he migrated to. Migration could also be for the purpose of religion, such as one who migrates from a non-Muslim land to a Muslim land. This is the migration about which the Prophet informed us that it does not stop, as in the hadeeth: “Migration does not stop until repentance stops, and repentance does not stop until the sun rises from the West.” [Ahmad and Abu Daawood]
Mirqaat al-Mafaateeh reads, “The Prophet by migration, here, meant moving from disbelief to belief, and from the land of disbelief to the land of Islam, and from sin to repentance.”
Dear brother, you should not forget the saying of the Prophet : “The migrant is the one who migrates from what Allaah has forbidden.” [Al-Bukhari]
Ibn Hajar said, “Migration is of two types: outward and inward: the inward migration is leaving the evil that the soul and devil order; and the outward migration is fleeing with the religion from temptations. It is as if the migrants were addressed with this so that they would not just rely on moving away from their homes to abide by the orders of the sharee'ah and its prohibitions.” [Fat-h Al-Baari]
Allaah knows best.
