Allah’s Sunnah With Those Who Insult His Messenger
“…And from the ways of Allah is that in regards to those who harm Allah and His Messenger whom the believers cannot punish, then Allah Himself takes sufficient revenge on behalf of His Messenger. For example, the story of Allah’s one-by-one destruction of those who mocked the Prophet (peace be upon him) is well known, as has been mentioned by the scholars of history and tafsir. They were a small group of the heads of Quraysh, including al-Walid bin Mughirah, al-‘As bin Wa’il, al-Aswadan bin ‘Abd al-Mutallib, Ibn ‘Abd Yaghuth, and al-Harith bin Qays.
Also, the Prophet (peace be upon him) wrote to Kisra (the king of Persia) and Caesar (the king of Rome), while neither of them had entered into Islam. However, Caesar respected the letter of the Messenger of Allah (peace be upon him), and treated his ambassador in a fine manner, so his kingdom was kept for him, and this is why it was said: “His kingdom remains for him among his descendants until today.” As for Kisra, he tore the letter of the Messenger of Allah into pieces and mocked him. As a result, Allah caused Kisra to be killed soon after, and caused his kingdom to be torn into pieces, and there did not remain for any of the future Kisras any kingdom, and this – and Allah Knows best – is in accordance with the phrase “the flesh of the scholars is poisonous.” So, how would it be with the flesh of the Prophets (peace be upon them)?
And in the ‘Sahih,’ it is narrated: “Allah the Exalted says: “Whoever declares his enmity to a close ally of Mine, then I declare war on him.”” So, how would it be in the case of the one who declares his enmity to the Prophets?
Whoever Allah declares war upon, then he will no doubt be fought!
If you read the stories of the Prophets mentioned in the Qur’an, then you will find that their people were destroyed the moment they began harming their Prophets by throwing at them the nastiest of words and actions. This is how the Children of Israel had humiliation thrown upon them, and this is how they earned the anger of Allah, and they had nobody to help them against Him – all of this, because they killed the Prophets without any right, in addition to their disbelief, as Allah mentioned in His Book. And you will not find anybody who ever harmed a Prophet from the Prophets – and did not repent from this – except that Allah would strike him with some type of calamity or disaster soon after. And we have previously mentioned the efforts of the Muslims in hastening their punishment of the disbelievers who insulted the Messenger of Allah (peace be upon him), and we mentioned many different examples of this, and this is a wide door of discussion that cannot be mentioned here in its entirety.
An example of this is what has been mentioned regarding a huge group of the Muslims in our times, when they were laying siege to the fortresses and cities of the Romans on the Syrian coast. They said: “We used to lay siege to the castle or city for a month or more without being able to penetrate it. As soon as we would hear that its people began insulting the Messenger of Allah (peace be upon him) and attacking his honor, our victory over them was suddenly and miraculously made quick and easy, and would not come beyond a day or two afterward. The gates of the area would open, and we would proceed to attack them severely. We would be extremely happy with this speedy victory when we heard their slander of him (peace be upon him), despite our hearts being filled with rage because of what they had said.”
And similar accounts were narrated from our trustworthy companions from Morocco, as their incidents with the Christians there were similar.
So, from the ways of Allah is that He sometimes punishes His enemies with a torment of His own, and He sometimes does so at the hands of His believing servants.”
