Leaving (postponing) (of the sacred months) is only an addition in disbelief. With it those who disbelieve are led astray. They make it (the postponed month) lawful one year and forbid it (the postponed month) another year in order to adjust the number (of the sacred) months that Allah has forbidden and make such forbidden ones lawful. The evil of their deeds is made fair-seeming to them. And Allah does not cause the disbelieving people to attain Guidance (Hidayet).
O you who believe (who wish to reach Allah before death)! What is the matter with you that when you are asked to go forth to struggle (struggling against your souls to render your spirit to Allah) (struggle against the disbelievers and your enemies) in the Way of Allah you cling (your spirit still did not start to its journey towards Allah) (you did not join the Islamic army to fight) heavily to the earth? Are you pleased with the life of this world rather than (rendering your spirit) the Hereafter? But little is the offering (provision, comfort) of this world as compared to (rendering the spirit back to Allah) the Hereafter.
If you do not march forth (having your spirit get on the Sirat-i Mustakim to reach Allah) (voluntarily go to war), He will torment you with a painful torment and will replace you by another people. You cannot harm Him at all in any way, and Allah has Power over all things.
If you do not help him (when you did not help him), Allah did help him (Rasul). When the disbelievers expelled him (when the disbelievers forced him to go out of Makkah) he was the second of the two, when they were both in the cave. When they were in the cave, he said to his companion: “Do not grieve, surely Allah is with us”. Then Allah sent down His Sakînah (calmness, tranquility) upon him and strengthened him with armies which you could not see. He (Allah) made lowest the word of those who disbelieved. And the Word of Allah, that is the highest and Allah is All-Mighty, All-Wise.
