If they are expelled, never will they go out with them; and if they are attacked (in fight), they will never help them; and if they do help them, they will turn their backs; so they will receive no help. Al-Hashr 59:12 ⧉
Tafsir:
When the Prophet Muhammad announced the banishment of the Banu al-Nadir, the hypocrites ostensibly rallied to their side. They asked the Banu al-Nadir to take a firm stand and assured them of their support. But the hypocrites uttered these words just to incite them to rise against Muslims; they were never sincere in their offer. So, when the Muslims besieged the Banu al-Nadir, nobody came to help them. This has been the character of self-interested people in every age.
