And the statement of Allah, the Exalted (in Surah At-Tawbah): "Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only knew. If it had been a near gain and an easy journey, they (the hypocrites), O Prophet, would certainly have followed you, but the journey (to Tabuk) seemed too far to them. And they will swear by Allah: 'If we had been able, we would certainly have gone forth with you.' They destroy their own selves, and Allah knows that they are surely liars." (the verse continues) And the statement of Allah: "O you who believe! What is the matter with you that, when you are told to go forth in the cause of Allah, you cling heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter." (up to) "And Allah is Able to do all things." It is narrated from Abdullah ibn Abbas (may Allah be pleased with them both) (in the explanation of the first verse) that it means: Go forth in separate groups for jihad. It is said that «ثبات» (plural) is «ثبة‏» .

Narrated Ibn `Abbas: On the day of the Conquest (of Mecca) the Prophet said, "There is no emigration after the Conquest but Jihad and intentions. When you are called (by the Muslim ruler) for fighting, go forth immediately." (See Hadith No. 42)
