O people, you recite this verse: ʿO you who believe! Take care of your own selves. If you follow the (right) guidance [and enjoin what is right (Islamic Monotheism and all that Islam orders one to do) and forbid what is wrong (polytheism, disbelief and all that Islam has forbidden)] no hurt can come to you from those who are in errorʿ [al-Ma’idah 5:105]. I heard the Messenger of Allah ﷺ say: “If the people see an evildoer and do not stop him, soon Allah will send His punishment upon them all.”
يا أَيُّهَا النَّاسُ إِنَّكُمْ تَقْرَؤُونَ هَذِهِ الْآيَةَ {يَا أَيُّهَا الَّذِينَ آمَنُوا عَلَيْكُمْ أَنْفُسَكُمْ لَا يَضُرُّكُمْ مَّنْ ضَلَّ إِذَا اهْتَدَيْتُمْ} [المائدة 105] وَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ النَّاسَ إِذَا رَأَوْا الظَّالِمَ فَلَمْ يَأْخُذُوا عَلَى يَدَيْهِ أَوْشَكَ أَنْ يَعُمَّهُمُ اللهُ بِعِقَابِهِ
