Chapter 1~Sincerity and Significance of Intentions in all Actions, Apparent and Hidden
3. Narrated Aishah (RA): Allah’s Messenger (pbuh) said, “There is no emigration after the conquest (of Makkah) but only Jihad [(striving and fighting in the cause of Allah) will continue] and good intention (seeking Allah’s Pleasure only); so if you are summoned to fight, go forth.” [Al-Bukhari and Muslim]
Commentary: When some country or region is regarded Dar-ul-Islam (land of Islam), it is not necessary to migrate from it to some other place. It is, however, obligatory to migrate from such regions which are Dar-ul-Kufr (land of infidels) and where it is difficult to adhere to Islamic injunction. It is evident from this Hadith that when it is not necessary to migrate from one Islamic country to another then it is also not permitted by the Shariah to leave an Islamic country to settle permanently in Dar-ul-Kufr only for the reason that the latter has plenty of wealth and social amenities. Unfortunately, present-day Muslims are afflicted with this disease. The transfer of their capital and talent to Dar-ul-Kufr is indeed very disturbing because on the one side these 2 factors are lending support to the economy of Bilad-ul-Kufr (countries of infidels) and on the other, obscene and indecent civilization of such countries is becoming increasingly popular among the Muslims.
