Hudhaifah reported the Messenger of Allah (ﷺ) as saying:Every people have Magians, and the Magians of this community are those who declare that there is no destination by Allah. If any one of them dies, do not attend his funeral, and if any one of them is ill, do not pay a sick visit to him. They are the partisans of the Antichrist (Dajjal), and Allah will surely join them with the Antichrist.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ عُمَرَ بْنِ مُحَمَّدٍ، عَنْ عُمَرَ، مَوْلَى غُفْرَةَ عَنْ رَجُلٍ، مِنَ الأَنْصَارِ عَنْ حُذَيْفَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لِكُلِّ أُمَّةٍ مَجُوسٌ وَمَجُوسُ هَذِهِ الأُمَّةِ الَّذِينَ يَقُولُونَ لاَ قَدَرَ مَنْ مَاتَ مِنْهُمْ فَلاَ تَشْهَدُوا جَنَازَتَهُ وَمَنْ مَرِضَ مِنْهُمْ فَلاَ تَعُودُوهُمْ وَهُمْ شِيعَةُ الدَّجَّالِ وَحَقٌّ عَلَى اللَّهِ أَنْ يُلْحِقَهُمْ بِالدَّجَّالِ " .
