It is narrated from Sayyiduna Abu Amir Ash'ari (may Allah be pleased with him) that one of them was martyred in the battle of Autas. The Noble Prophet (peace and blessings be upon him) said to him: O Abu Amir! Why did you not change this evil (i.e., why did you not stop him from it)? In response, he recited this verse: {یَا أَ یُّہَا الَّذِینَ آمَنُوْا عَلَیْکُمْ أَ نْفُسَکُمْ لَا یَضُرُّکُمْ مَنْ ضَلَّ إِذَا اہْتَدَیْتُمْ} … O you who have believed! Upon you is [responsibility for] yourselves. Those who have gone astray will not harm you when you have been guided. Upon hearing this, the Noble Prophet (peace and blessings be upon him) became angry and said: Where have you gone? The meaning of this verse is that O believers! When you have become rightly guided, then the misguided disbelievers will not harm you.
