Going out and roaming to convey Da`wah

Q 22: Is traveling and roaming about the world to make Da`wah (calling to Islam) considered a 'permanent migration' or is it something wrong based on the Hadith - that we do not know whether it is Sahih (authentic) or not - which reads: "There is no traveling after the Liberation of Makkah, but Jihad 'fighting/striving in the cause of Allah' and sincere intention"? Please provide us with your beneficial answer.

A: The correct wording of the Hadith is: There is no Hijrah after the Liberation of Makkah, but Jihad and sincere intention. When you are asked to set out (for the cause of Islam) you should set out. (Related in the Two Sahih Books of Hadith ', meaning, Al-Bukhari and Muslim' on the authority of Ibn `Abbas, may Allah be pleased with them both). The Hijrah which is mentioned in the Hadith refers to the one that was an individual obligation on all Muslims to leave their homeland, Makkah and go to Al-Madinah after the Opening of Makkah. However, other forms of Hijrah (migration to lands other than a believer's homeland) are still applicable such as Hijrah for sake of Jihad, for a good intention such as fleeing from the home of Kafirs (disbelievers), seeking knowledge, or escaping to safeguard one's Din 'religion' against Fitnah (temptation). Thus, the Hadith which is mentioned above is confined to Hijrah from Makkah for it has already become a Muslim place. As for Hijrah from the countries of Kafirs to Muslim countries, it will remain applicable until the Day of Resurrection.On the other hand, Da`wah (calling to Islam) and spreading Islam in the countries of the Kafirs is (Part No. 12; Page No. 261) a great benefit and a lofty deed. Any fatigue or harm that a Muslim may face and any money that he may spend for the sake of Da`wah is considered a sort of Jihad which he will be rewarded for. Nevertheless, it is not identical to Jihad Al-Kuffar (fighting the disbelievers) but each one of them is beneficial and greatly rewarded. It is worthy to mention here that it is related in the Two Sahih Books of Hadith from the Hadith which is narrated by Sahl ibn Sa`d Al-Sa`idy (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said to `Aly ibn Abu Talib (may Allah be pleased with him) on the day of Khaybar: ... By Allah, if Allah guides aright even one man through you that is better for you than to possess the most valuable of the camels. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
