[Machine] The Prophet of Allah, ﷺ , said, "Pray behind every righteous person and sinner, and pray for every righteous person and sinner, and strive with every righteous person and sinner."  

أَنَّ رَسُولَ اللهِ صَلَّى الله عَلَيهِ وَسَلَّمَ قَالَ صَلُّوا خَلْفَ كُلِّ بَرٍّ وَفَاجِرٍ وَصَلُّوا عَلَى كُلِّ بَرٍّ وَفَاجِرٍ وَجَاهِدُوا مَعَ كُلِّ بَرٍّ وَفَاجِرٍ  

[Machine] The Prophet ﷺ was approached by a man who had killed himself with a weapon. The Prophet did not offer funeral prayer for him. This is a narration from Awf ibn Sallam. In another narration from Ahmad ibn Yunus, it is mentioned that a man became sick and screamed in pain, so another man came to the Messenger of Allah ﷺ and informed him that the man had died. The Prophet asked him how he knew, and the man replied that he had screamed in pain. The Messenger of Allah ﷺ said that he had not actually died. Then, the man went back and found that the man had indeed killed himself with a weapon, so he went back to the Messenger of Allah ﷺ and informed him. The Prophet asked him how he knew, and the man replied that he had seen him kill himself with a weapon. The Prophet then said that he would not offer funeral prayer for him.  

أُتِيَ النَّبِيُّ ﷺبِرَجُلٍ قَتَلَ نَفْسَهَ بِمَشَاقِصَ فَلَمْ يُصَلِّ عَلَيْهِ هَذَا لَفْظُ حَدِيثِ عَوْنِ بْنِ سَلَّامٍ وَفِي حَدِيثِ أَحْمَدَ بْنِ يُونُسَ قَالَ مَرِضَ رَجُلٌ فَصِيحَ عَلَيْهِ فَجَاءَ رَجُلٌ إِلَى رَسُولِ اللهِ ﷺفَقَالَ إِنَّهُ مَاتَ قَالَ مَا يُدْرِيكَ قَالَ إِنَّهُ صِيحَ عَلَيْهِ قَالَ رَسُولُ اللهِ ﷺإِنَّهُ لَمْ يَمُتْ ثُمَّ انْطَلَقَ الرَّجُلُ فَرَآهُ قَدْ نَحَرَ نَفْسَهُ بِمَشَاقِصَ فَانْطَلَقَ إِلَى رَسُولِ اللهِ ﷺفَأَخْبَرَهُ أَنَّهُ مَاتَ فَقَالَ مَا يُدْرِيكَ قَالَ رَأَيْتُهُ نَحَرَ نَفْسَهَ بِمَشَاقِصَ قَالَ إِذًا لَا أُصَلِّي عَلَيْهِ
