The same thing has been said in the Holy Qur'an thus...

The same thing has been said in the Holy Qur'an thus: They do not believe in truth and they exactly follow the Sunnah (tradition) of the past people," (Surah al-Hijr, 15: 13) i.e. there is no hope that these infidels of Makkah who persist in their enmity and grudge against the Prophet of Allah will believe. They do not believe but their matter is quite clear and Our Sunnah (method) with regard to those who lived before them and persisted in their infidelity is known.

We shall deal with them in the same way in which We dealt with those persons. Allah say: Had the disbelievers fought against you, they would take to flight and would have found no guardian or helper.

This is the Sunnah (law) of Allah which existed before you, and you will never find any change in Allah's system, (Surah al-Fath, 48:23) If the polytheists of Makkah had fought against you in Hudaibiya they would not have gained anything and would have taken to flight and thereafter they would not have found any refuge or helper. This is the way in which Allah has dealt with the unbelievers earlier and the law and the Sunnah of Allah do not change.

It means that one of the laws of Allah is that faith is the source of victory and domination over the enemy and it is not only you and the polytheists of Makkah but out of every two parties which grapple with each other Allah grants victory to that party which joins the battle with the stimulant of faith. Allah says: Evil plots only affect the plotters. Do they expect anything other than (Allah's) law (torment) with those who lived before?

You will never find any change in the tradition of Allah nor will you find any alteration in it. (Surah al-Fatir, 35: 43) That means: These people who do not give up idol-worship and make evil plots so as to hinder the advancement of Islam should know that evil plots eventually recoil on those who make them.

And if they expect that We shall treat them in a way other than that in which We treated the people of the past, it is an inopportune expectation because Allah's Sunnah does not change and deceit and fraud can never be the source of honor and advancement. Allah says: Their faith could not avail against Our punishment. Such is Allah's prevailing Sunnah (law) among His servants in the past. Thus the disbelievers are ruined. (Surah Mumin, 40:85) i.e.
