A son of one of the daughters of the Prophet ﷺ was dying, so she sent a person to call the Prophet. He sent (her a message), "What ever Allah takes is for Him, and whatever He gives is for Him, and everything has a limited fixed term (in this world) so she should be patient and hope for Allah's reward." She then sent for him again, swearing that he should come. Messenger of Allah ﷺ got up, and so did Muʿadh bin Jabal, Ubai bin Kaʿb and 'Ubada bin As-Samit. When he entered (the house), they gave the child to Messenger of Allah ﷺ while its breath was disturbed in his chest. (The sub-narrator said: I think he said, "...as if it was a water skin.") Messenger of Allah ﷺ started weeping whereupon Saʿd bin 'Ubada said, "Do you weep?" The Prophet ﷺ said, "Allah is merciful only to those of His slaves who are merciful (to others).  

كَانَ ابْنٌ لِبَعْضِ بَنَاتِ النَّبِيِّ ﷺ يَقْضِي فَأَرْسَلَتْ إِلَيْهِ أَنْ يَأْتِيَهَا فَأَرْسَلَ إِنَّ لِلَّهِ مَا أَخَذَ وَلَهُ مَا أَعْطَى وَكُلٌّ إِلَى أَجَلٍ مُسَمًّى فَلْتَصْبِرْ وَلْتَحْتَسِبْ فَأَرْسَلَتْ إِلَيْهِ فَأَقْسَمَتْ عَلَيْهِ فَقَامَ رَسُولُ اللَّهِ ﷺ وَقُمْتُ مَعَهُ وَمُعَاذُ بْنُ جَبَلٍ وَأُبَىُّ بْنُ كَعْبٍ وَعُبَادَةُ بْنُ الصَّامِتِ فَلَمَّا دَخَلْنَا نَاوَلُوا رَسُولَ اللَّهِ ﷺ الصَّبِيَّ وَنَفْسُهُ تَقَلْقَلُ فِي صَدْرِهِ حَسِبْتُهُ قَالَ كَأَنَّهَا شَنَّةٌ فَبَكَى رَسُولُ اللَّهِ ﷺ فَقَالَ سَعْدُ بْنُ عُبَادَةَ أَتَبْكِي فَقَالَ إِنَّمَا يَرْحَمُ اللَّهُ مِنْ عِبَادِهِ الرُّحَمَاءَ  

The Prophet ﷺ said, "Paradise and Hell (Fire) quarrelled in the presence of their Lord. Paradise said, 'O Lord! What is wrong with me that only the poor and humble people enter me ?' Hell (Fire) said, I have been favored with the arrogant people.' So Allah said to Paradise, 'You are My Mercy,' and said to Hell, 'You are My Punishment which I inflict upon whom I wish, and I shall fill both of you.'" The Prophet added, "As for Paradise, (it will be filled with good people) because Allah does not wrong any of His created things, and He creates for Hell (Fire) whomever He will, and they will be thrown into it, and it will say thrice, 'Is there any more, till Allah (will put) His Foot over it and it will become full and its sides will come close to each other and it will say, 'Qat! Qat! Qat! (Enough! Enough! Enough!) .  

عَنِ النَّبِيِّ ﷺ قَالَ اخْتَصَمَتِ الْجَنَّةُ وَالنَّارُ إِلَى رَبِّهِمَا فَقَالَتِ الْجَنَّةُ يَا رَبِّ مَا لَهَا لاَ يَدْخُلُهَا إِلاَّ ضُعَفَاءُ النَّاسِ وَسَقَطُهُمْ وَقَالَتِ النَّارُ يَعْنِي أُوثِرْتُ بِالْمُتَكَبِّرِينَ فَقَالَ اللَّهُ تَعَالَى لِلْجَنَّةِ أَنْتِ رَحْمَتِي وَقَالَ لِلنَّارِ أَنْتِ عَذَابِي أُصِيبُ بِكِ مَنْ أَشَاءُ وَلِكُلِّ وَاحِدَةٍ مِنْكُمَا مِلْؤُهَا قَالَ فَأَمَّا الْجَنَّةُ فَإِنَّ اللَّهَ لاَ يَظْلِمُ مِنْ خَلْقِهِ أَحَدًا وَإِنَّهُ يُنْشِئُ لِلنَّارِ مَنْ يَشَاءُ فَيُلْقَوْنَ فِيهَا فَتَقُولُ هَلْ مِنْ مَزِيدٍ ثَلاَثًا حَتَّى يَضَعَ فِيهَا قَدَمَهُ فَتَمْتَلِئُ وَيُرَدُّ بَعْضُهَا إِلَى بَعْضٍ وَتَقُولُ قَطْ قَطْ قَطْ  

The Prophet ﷺ said, "Some people will be scorched by Hell (Fire) as a punishment for sins they have committed, and then Allah will admit them into Paradise by the grant of His Mercy. These people will be called, 'Al-Jahannamiyyin' (the people of Hell).  

عَنِ النَّبِيِّ ﷺ قَالَ لَيُصِيبَنَّ أَقْوَامًا سَفْعٌ مِنَ النَّارِ بِذُنُوبٍ أَصَابُوهَا عُقُوبَةً ثُمَّ يُدْخِلُهُمُ اللَّهُ الْجَنَّةَ بِفَضْلِ رَحْمَتِهِ يُقَالُ لَهُمُ الْجَهَنَّمِيُّونَ وَقَالَ هَمَّامٌ حَدَّثَنَا قَتَادَةٌ حَدَّثَنَا أَنَسٌ عَنِ النَّبِيِّ ﷺ
