Hadith 5140
عَنْ حُذَيْفَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «وَالَّذِي نَفْسِي بِيَدِهِ لَتَأْمُرُنَّ بِالْمَعْرُوفِ وَلَتَنْهَوُنَّ عَنِ الْمُنْكَرِ أَوْ لَيُوشِكَنَّ اللَّهُ أَنْ يَبْعَثَ عَلَيْكُمْ عَذَابًا مِنْ عِنْدِهِ ثُمَّ لَتَدْعُنَّهُ وَلَا يُسْتَجَاب لكم» . رَوَاهُ التِّرْمِذِيّ
It is narrated from Hudhaifah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "By Him in Whose hand is my soul! You must certainly enjoin good and forbid evil, otherwise it is near that Allah will send His punishment upon you, then you will supplicate to Him but He will not accept your supplications." Hasan, narrated by Tirmidhi.
