Warning against Not hating Sins
Malik ibn Dinar says: Allah asked his angels to destroy a certain town. The angels said that there lived in that town a devoted servant of His busy praying to Him. Came the command: Let him too taste the punishment because he never showed his anger against people disobeying Us and committing sins openly, not even with a sign of it on his face.
To Sayyidna Yusha' ibn Nun عليه السلام, (Joshua) the Israelite prophet, Allah Almighty revealed that one hundred thousand of his people will be destroyed by a punishment. Of them, forty thousand were righteous and sixty thousand, evil. Sayyidna Yusha' said: O Lord, the ruin of the evil is obvious but why the good ones? It was said: The good ones had friendly relations with the bad ones. Together, they ate and drank and enjoyed life and never frowned on people sinning and disobeying their Creator. (Details of all these narrations can be seen in Al-Bahr al-Muhit).
Verses 64 - 67
وَقَالَتِ الْيَهُودُ يَدُ اللَّهِ مَغْلُولَةٌ ۚ غُلَّتْ أَيْدِيهِمْ وَلُعِنُوا بِمَا قَالُوا ۘ بَلْ يَدَاهُ مَبْسُوطَتَانِ يُنفِقُ كَيْفَ يَشَاءُ ۚ وَلَيَزِيدَنَّ كَثِيرًا مِّنْهُم مَّا أُنزِلَ إِلَيْكَ مِن رَّبِّكَ طُغْيَانًا وَكُفْرًا ۚ وَأَلْقَيْنَا بَيْنَهُمُ الْعَدَاوَةَ وَالْبَغْضَاءَ إِلَىٰ يَوْمِ الْقِيَامَةِ ۚ كُلَّمَا أَوْقَدُوا نَارًا لِّلْحَرْبِ أَطْفَأَهَا اللَّهُ ۚ وَيَسْعَوْنَ فِي الْأَرْضِ فَسَادًا ۚ وَاللَّهُ لَا يُحِبُّ الْمُفْسِدِينَ
وَلَوْ أَنَّ أَهْلَ الْكِتَابِ آمَنُوا وَاتَّقَوْا لَكَفَّرْنَا عَنْهُمْ سَيِّئَاتِهِمْ وَلَأَدْخَلْنَاهُمْ جَنَّاتِ النَّعِيمِ
وَلَوْ أَنَّهُمْ أَقَامُوا التَّوْرَاةَ وَالْإِنجِيلَ وَمَا أُنزِلَ إِلَيْهِم مِّن رَّبِّهِمْ لَأَكَلُوا مِن فَوْقِهِمْ وَمِن تَحْتِ أَرْجُلِهِم ۚ مِّنْهُمْ أُمَّةٌ مُّقْتَصِدَةٌ ۖ وَكَثِيرٌ مِّنْهُمْ سَاءَ مَا يَعْمَلُونَ
يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنزِلَ إِلَيْكَ مِن رَّبِّكَ ۖ وَإِن لَّمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ ۚ وَاللَّهُ يَعْصِمُكَ مِنَ النَّاسِ ۗ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الْكَافِرِين
And the Jews said, "Allah's hand is fettered." Fettered are their own hands, and cursed are they for what they said. In fact, His hands are well-extended. He gives as He wills. And what has been sent down to you from your Lord shall certainly increase many of them in rebellion and disbelief. And We have put enmity and hatred amongst them lasting to the Day of Doom. Whenever they lit the flame of war, Allah puts it out. And they run about on the earth spreading mischief. And Allah does not like the mischief-makers.
And if the People of the Book had believed and feared, We would have written off their evil deeds and would have surely admitted them to the Gardens of Bliss.  And if they had upheld the Torah and the Injil and what had been sent down to them from their Lord, they would have surely had plenty to eat from above them and from beneath them. Among them are moderate people. As for most of them, evil is what they do. 
O Messenger, convey all that has been sent down to you from your Lord. And if you do not, then, you have not conveyed His message (at all). And Allah shall protect you from the people. Surely, Allah does not take the disbelieving people to the right path. 
Some conditions of the Jews were mentioned in the previous verses. More particular ones appear in the verses cited above, specially the ones identified with Nabbash son of Qays and Fenhas, the chief of the Jewish tribe of Qaiynuqa' who uttered words of affront with reference to Almighty Allah, the description of which follows. Thereupon, ' the opening verse was revealed. (As in Al-lubab, from Sayyidna ibn 'Abbas narrated by Al-Tabarani and Abu Al-Shaykh).
The first verse begins with the words: وَقَالَتِ الْيَهُودُ (And the Jews said). It mentions what was a grave offence and an utterly undignified remark for any human being to make. They were wretched enough to (God forbid) say that Allah's hand is tied up.
The background in which this was said was that Allah Almighty had given to the Jews of Madinah extended means and money. But, when the Holy Prophet (SM) came to Madinah, they heard the call of Islam, yet they remained unmoved because they were more interested in holding on to their communal hegemony and the money they received through offerings based on their self-perpetuating customs. So, they turned against what was the call of truth and took a hostile stand against the Holy Prophet (SM) himself. Then, as a punishment of this behaviour of theirs, Almighty Allah turned their affluent material circumstances into what was materially straightened for them and they faced poverty. Thereupon, all frustrated and offguard, they started uttering words to the effect that (God forbid) the Divine treasure seems to be running short or, perhaps, Allah has the sen to become miserly. It was in answer to them that it was said in this verse that the hands to be tied up will be their own hands who are saying what they are saying and cursed they shall be when punishment visits them in the Hereafter, and in the present world as well, when it comes to them in the form of disgrace. As for the hands of Allah, they are always open and well-extended, and His generosity has been there since ever and shall remain for ever. But, He Himself is Independent, free of need, yet the master of all means. Then, along with this, He is Wise too. He gives and gives in His Wisdom. Means are extended for whom He wills in His Wisdom and means are straightened for whom He wills in His Wisdom.
