The duty of forsakes his home in the cause of Allah and the reward

AN-NISA (WOMEN) : 97-100

4:97. When angels take the souls of those who die in sin against their souls, they say: "In what (plight) Were ye?" They reply: "Weak and oppressed Were we in the earth." They say: "Was not the earth of Allah spacious enough for you to move yourselves away (From evil)?" Such men will find their abode in Hell,- What an evil refuge! -

4:98. Except those who are (really) weak and oppressed - men, women, and children - who have no means in their power, nor (a guide-post) to their way.
4:99. For these, there is hope that Allah will forgive: For Allah doth blot out (sins) and forgive again and again.
4:100. He who forsakes his home in the cause of Allah, finds in the earth Many a refuge, wide and spacious: Should he die as a refugee from home for Allah and His Messenger, His reward becomes due and sure with Allah: And Allah is Oft-forgiving, Most Merciful.
