Encouragement to fight the Disbelievers, and some Benefits of fighting Them
These Ayat encourage, direct and recommend fighting against the idolators who break the terms of their covenants, those who tried to expel the Messenger from Makkah. Allah said in other Ayat,
(And (remember) when the disbelievers plotted against you to imprison you, or to kill you, or to expell you; they were plotting and Allah too was plotting; and Allah is the best of those who plot.) 8:30,
1. Finally, it was said: وَيَتُوبُ اللَّـهُ عَلَىٰ مَن يَشَاءُ (And Allah relents to whomsoever He wills -15). This tells us that there will be an added gain as a result of this Jihad. There will be many from among the enemies who will have the taufiq of Islam. They will become Muslims. So, there were many arrogant ones at the time of the Conquest of Makkah who were put to disgrace while there were many others who embraced Islam.
History proves that the circumstances and events predicted in these verses were witnessed one by one as pointed out by the Holy Qur'an. Therefore, these verses contain many miracles.
Tazkirul Quran
Maulana Wahiduddin Khan
The root of all wisdom is fear of God. The fear of God develops in man the readiness to accept the Truth; it awakens in man a certain consciousness that enables him to see realities in their original form. That is why it does not take the God-fearing man long to understand the Divine plan. He comes to know the will of God and dedicates himself to it with full confidence. He starts moving on that right path which ultimately leads to success. The fear of God makes a man’s eye tearful, and before God, it is only the tearful eye which is destined to be cooled in this world as well as in the Hereafter.
