The Campaign against Banu Qurayzah
We have already noted that when the Confederates came and camped outside Al-Madinah, Banu Qurayzah broke the covenant that existed between them and the Messenger of Allah ﷺ. This happened by the agency of Huyay bin Akhtab An-Nadari, may Allah curse him, who entered their stronghold and would not leave their leader, Ka`b bin Asad, alone until he agreed to break the covenant. Among the things that he said to him was, "Woe to you! This is the opportunity for glory. The Quraysh and their company of men from various tribes, and the Ghatafan and their followers, have come to you, and they will stay here until they eliminate Muhammad ﷺ and his companions." Ka`b said to him, "No, by Allah, this is the opportunity for humiliation. Woe to you, O Huyay, you are a bad omen. Leave us alone." But Huyay kept trying to persuade him until he agreed to his request. He laid down the condition that if the Confederates went away without doing anything, he Huyay would join them in their stronghold and would share their fate. When Banu Qurayzah broke their covenant and news of this reached the Messenger of Allah ﷺ , he and the Muslims were very distressed by that. When Allah helped him by suppressing his enemy and driving them back disappointed and lost, having gained nothing, the Messenger of Allah ﷺ returned to Al-Madinah in triumph and the people put down their weapons. While the Messenger of Allah ﷺ was washing off the dust of battle in the house of Umm Salamah, may Allah be pleased with her, Jibril, upon him be peace, came to him wearing a turban of brocade, riding on a mule on which was a cloth of silk brocade. He said, "Have you put down your weapons, O Messenger of Allah" He said, "Yes." He said, "But the angels have not put down their weapons. I have just now come back from pursuing the people." Then he said: "Allah, may He be blessed and exalted, commands you to get up and go to Banu Qurayzah." According to another report, "What a fighter you are! Have you put down your weapons" He said, "Yes." He said, "But we have not put down our weapons yet, get up and go to these people." He said: "Where" He said, "Banu Qurayzah, for Allah has commanded me to shake them." So the Messenger of Allah ﷺ got up immediately, and commanded the people to march towards Banu Qurayzah, who were a few miles from Al-Madinah. This was after Salat Az-Zuhr. He said,
Continue reading the tafsir of ayahs 26–27 The second state mentioned here is that of the hypocrites for they had started saying that the promises of Allah and His Rasul ﷺ were a web of deception: إِذْ يَقُولُ الْمُنَافِقُونَ وَالَّذِينَ فِي قُلُوبِهِم مَّرَضٌ مَّا وَعَدَنَا اللَّـهُ وَرَسُولُهُ إِلَّا غُرُورًا (And (remember) when the hypocrites and those having malady in their hearts were saying, "Allah and His messenger did not promise us but deceitfully; -12). This was an externalized demonstration of their inner disbelief. Onward from here, mention has been made of two groups of hypocrites who were practically a part of the Jihad effort along with Muslims, though outwardly only. One of the two groups started running without any permission saying: وَإِذْ قَالَت طَّائِفَةٌ مِّنْهُمْ يَا أَهْلَ يَثْرِبَ لَا مُقَامَ لَكُمْ فَارْجِعُوا (and when a group of them said, "0 people of Yathrib (Madinah), there is no place for you to stay; so go back. - 13" And the other group requested the permission of the Holy Prophet ﷺ to go back on the basis of false excuses. Their conduct has been mentioned as: وَيَسْتَأْذِنُ فَرِيقٌ مِّنْهُمُ النَّبِيَّ يَقُولُونَ إِنَّ بُيُوتَنَا عَوْرَةٌ (And a group of them was seeking permission (to leave) from the prophet, saying, "In fact our homes are vulnerable," while they were not vulnerable - 13). Thus, the Qur'an exposed the hollowness of their excuses as a pack of lies. The truth of the matter was no more than that they intended to run from the battlefront:إِن يُرِيدُونَ إِلَّا فِرَارًا (They wanted nothing but to escape - 13). Taken up in the next several verses is their mischief-making and enmity with Muslims following which their sad end has been pointed out.
Continue reading the tafsir of ayahs 13–27 At the Battle of Ahzab, or the Trenches, conditions were very severe. But, in this battle the stage of regular fighting was never reached. Almighty God sent stormy winds and an army of angels against the enemies and terrified them to such an extent that they themselves fled the battlefield. The Jews of Madinah (the Banu Qurayzah) had entered into a pact of peace with the Muslims, but on the occasion of the Battle of Ahzab, they betrayed the Muslims. In breach of the pact, they supported the idolaters. Therefore, when the army of the attackers left Madinah, the Prophet Muhammad, as ordained by God, invaded the areas occupied by the Banu Qurayzah and the Islamic forces besieged their forts. The siege lasted for twenty five days. When they surrendered, everything that they possessed was forfeited.
