'Someone who does not show mercy will not be shown mercy.'  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ لاَ يَرْحَمُ لاَ يُرْحَمُ  

Jarir ibn 'Abdullah said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'Allah will not show mercy to someone who does not show mercy to people."  

قَالَ رَسُولُ اللهِ ﷺ لاَ يَرْحَمُ اللَّهُ مَنْ لا يَرْحَمُ النَّاسَ  

Same as 97.  

قَالَ رَسُولُ اللهِ ﷺ مَنْ لاَ يَرْحَمُ النَّاسَ لا يَرْحَمُهُ اللَّهُ  

'A'isha said, "Some bedouins came to the Prophet, may Allah bless him and grant him peace. One of their men said to him, 'Messenger of Allah, do you kiss children? By Allah, we do not kiss them.' The Messenger of Allah, may Allah bless him and grant him peace, said, 'Can I put mercy in your hearts after Allah has removed it from them?'"  

عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ أَتَى النَّبِيَّ ﷺ نَاسٌ مِنَ الأعْرَابِ فَقَالَ لَهُ رَجُلٌ مِنْهُمْ يَا رَسُولَ اللهِ أَتُقَبِّلُونَ الصِّبْيَانَ فَوَاللَّهِ مَا نُقَبِّلُهُمْ فَقَالَ رَسُولُ اللهِ ﷺ أَوَ أَمْلِكُ إِنْ كَانَ اللَّهُ عَزَّ وَجَلَّ نَزَعَ مِنْ قَلْبِكَ الرَّحْمَةَ؟  

Abu 'Uthman reported that 'Umar wanted to appoint a man as governor. The governor said, "I have such-and-such a number of children and I have never kissed any of them." 'Umar said, "Allah Almighty will only show mercy to the kindest of His slaves."  

أَنَّ عُمَرَ رَضِيَ اللَّهُ عَنْهُ اسْتَعْمَلَ رَجُلاً فَقَالَ الْعَامِلُ إِنَّ لِي كَذَا وَكَذَا مِنَ الْوَلَدِ مَا قَبَّلْتُ وَاحِدًا مِنْهُمْ فَزَعَمَ عُمَرُ أَوْ قَالَ عُمَرُ إِنَّ اللَّهَ عَزَّ وَجَلَّ لاَ يَرْحَمُ مِنْ عِبَادِهِ إِلاَّ أَبَرَّهُمْ
