Imaam Shanqeetee (rahimahullaah) stated:
The Great Qur’aan has given guidance to stop this problem through the most appropriate and upright paths. Allaah clarified that the remedy for this is linked to turning to Him truthfully, the strength of faith in Him and reliance on Him. That is because Allaah is All-Strong and All-Mighty, the Overwhelming and Absolute Subduer of everything, Who is never overcome. So whoever is truly an ally of Allaah, it is not possible to gain the upper hand over such a person.
And from the clear proofs regarding this is when the disbelievers laid that great siege against the Muslims during the battle of the Confederates about which Allaah stated:
إِذۡ جَآءُوكُم مِّن فَوۡقِكُمۡ وَمِنۡ أَسۡفَلَ مِنكُمۡ وَإِذۡ زَاغَتِ ٱلۡأَبۡصَـٰرُ وَبَلَغَتِ ٱلۡقُلُوبُ ٱلۡحَنَاجِرَ وَتَظُنُّونَ بِٱللَّهِ ٱلظُّنُونَا۟
هُنَالِكَ ٱبۡتُلِىَ ٱلۡمُؤۡمِنُونَ وَزُلۡزِلُواْ زِلۡزَالاً۬ شَدِيدً۬ا
”When they came upon you from above you and from below you, and when the eyes grew wild and the hearts reached to the throats, and you were harbouring doubts about Allah. There, the believers were tried and shaken with a mighty shaking.” Therefore, the remedy for this is what we have already mentioned (i.e. Imaan, turning to Allaah and reliance on Him). Look at the severity of this military siege and its severe effects on the Muslims and addition to the fact that they were politically and economically cut off by all the people of the earth at that time! So when you are aware of this, then you should know that the remedy for this great affair which put an end to this great difficulty is what Allaah stated in Soorah Al-Ahzaab, as follows:
[وَلَمَّا رَءَا ٱلۡمُؤۡمِنُو نَ ٱلۡأَحۡزَابَ قَالُواْ هَـٰذَا مَا وَعَدَنَا ٱللَّهُ وَرَسُولُهُ ۥ وَصَدَقَ ٱللَّهُ وَرَسُولُهُ ۥۚ وَمَا زَادَهُمۡ إِلَّآ إِيمَـٰنً۬ا وَتَسۡلِيمً۬ا
And when the believers saw Al-Ahzab (the Confederates), they said: “This is what Allah and His Messenger (Muhammad) had promised us, and Allah and His Messenger (Muhammad) had spoken the truth, and it only added to their faith and to their submissiveness (to Allah).
This perfect Imaan in Allaah; (this) Great Submission to Him; (this) dependence and reliance on Him was the reason that put an end to that great difficulty. And indeed Allaah clarified the fruits of this remedy, saying:
[وَرَدَّ ٱللَّهُ ٱلَّذِينَ كَفَرُواْ بِغَيۡظِهِمۡ لَمۡ يَنَالُواْ خَيۡرً۬اۚ وَكَفَى ٱللَّهُ ٱلۡمُؤۡمِنِينَ ٱلۡقِتَالَۚ وَكَانَ ٱللَّهُ قَوِيًّا عَزِيزً۬ا ]
[وَأَنزَلَ ٱلَّذِينَ ظَـٰهَرُوهُم مِّنۡ أَهۡلِ ٱلۡكِتَـٰبِ مِن صَيَاصِيهِمۡ وَقَذَفَ فِى قُلُوبِهِمُ ٱلرُّعۡبَ فَرِيقً۬ا تَقۡتُلُونَ وَتَأۡسِرُونَ فَرِيقً۬ا ]
[وَأَوۡرَثَكُمۡ أَرۡضَہُمۡ وَدِيَـٰرَهُمۡ وَأَمۡوَٲلَهُمۡ وَأَرۡضً۬ا لَّمۡ تَطَـُٔوهَاۚ وَكَانَ ٱللَّهُ عَلَىٰ ڪُلِّ شَىۡءٍ۬ قَدِيرً۬ا ]
”And Allah drove back those who disbelieved in their rage; they gained no advantage (booty, etc.). Allah sufficed for the believers in the fighting (by sending against the disbelievers a severe wind and troops of angels). And Allah is Ever All-Strong, All-Mighty. And those of the people of the Scripture who backed them (the disbelievers) Allah brought them down from their forts and cast terror into their hearts, (so that) a group (of them) you killed, and a group (of them) you made captives. And He caused you to inherit their lands, and their houses, and their riches, and a land which you had not trodden (before). And Allah is Able to do all things.
This is what Allaah aided them with against their enemies. Neither did they have an idea nor did they know that they were aided with the angels and the wind. Allaah (The Most High) said:
[يَـٰٓأَيُّہَا ٱلَّذِينَ ءَامَنُواْ ٱذۡكُرُواْ نِعۡمَةَ ٱللَّهِ عَلَيۡكُمۡ إِذۡ جَآءَتۡكُمۡ جُنُودٌ۬ فَأَرۡسَلۡنَا عَلَيۡہِمۡ رِيحً۬ا وَجُنُودً۬ا لَّمۡ تَرَوۡهَاۚ وَڪَانَ ٱللَّهُ بِمَا تَعۡمَلُونَ بَصِيرًا ]
”O you who believe! Remember Allah’s Favour to you, when there came against you hosts, and We sent against them a wind and forces that you saw not [i.e. troops of angels during the battle of Al-Ahzab (the Confederates)]. And Allah is Ever All-Seer of what you do.”
