"Usamah bin Zaid told me: 'The daughter of the Prophet sent word to him telling him: A son of mine is dying, come to us. He sent word to her, conveying his greeting of salam and saying: "To Allah belongs that which He takes and that which He gives, and everything has an appointed time with Allah. Let her be patient and seek reward." She sent word to him adjuring him to go to her. So he got up and went, accompanied by Sa'd bin 'Ubadah, Muadh bin Jabal, Ubayy bin Kab Zaid bin Thabit and some other men. The boy was lifted up to the Messenger of Allah, with the death rattle sounding in him, and his eyes filled with tears. Sa'd said: "O Messenger of Allah, what is this?" he said: "This is compassion which Allah has created in the hearts of His slaves. Allah has mercy on His compassionate slaves."  

أَرْسَلَتْ بِنْتُ النَّبِيِّ ﷺ إِلَيْهِ أَنَّ ابْنًا لِي قُبِضَ فَأْتِنَا فَأَرْسَلَ يَقْرَأُ السَّلاَمَ وَيَقُولُ إِنَّ لِلَّهِ مَا أَخَذَ وَلَهُ مَا أَعْطَى وَكُلُّ شَىْءٍ عِنْدَ اللَّهِ بِأَجَلٍ مُسَمًّى فَلْتَصْبِرْ وَلْتَحْتَسِبْ فَأَرْسَلَتْ إِلَيْهِ تُقْسِمُ عَلَيْهِ لَيَأْتِيَنَّهَا فَقَامَ وَمَعَهُ سَعْدُ بْنُ عُبَادَةَ وَمُعَاذُ بْنُ جَبَلٍ وَأُبَىُّ بْنُ كَعْبٍ وَزَيْدُ بْنُ ثَابِتٍ وَرِجَالٌ فَرُفِعَ إِلَى رَسُولِ اللَّهِ ﷺ الصَّبِيُّ وَنَفْسُهُ تَقَعْقَعُ فَفَاضَتْ عَيْنَاهُ فَقَالَ سَعْدٌ يَا رَسُولَ اللَّهِ مَا هَذَا قَالَ هَذَا رَحْمَةٌ يَجْعَلُهَا اللَّهُ فِي قُلُوبِ عِبَادِهِ وَإِنَّمَا يَرْحَمُ اللَّهُ مِنْ عِبَادِهِ الرُّحَمَاءَ  

"I heard Anas say: 'The Messenger of Allah said: True patience is that which comes at the first blow."'  

قَالَ رَسُولُ اللَّهِ ﷺ الصَّبْرُ عِنْدَ الصَّدْمَةِ الأُولَى  

a man came to the Prophet accompanied by a son of his. He said to him: "Do you love him?" He said: "May Allah love you as I love him." Then he (the son) died and he noticed his absence and asked about him. He said: "Will it not make you happy to know that you will not come to any of the gates of Paradise but you will find him there, trying to open it for you?"  

أَنَّ رَجُلاً أَتَى النَّبِيَّ ﷺ وَمَعَهُ ابْنٌ لَهُ فَقَالَ لَهُ أَتُحِبُّهُ فَقَالَ أَحَبَّكَ اللَّهُ كَمَا أُحِبُّهُ فَمَاتَ فَفَقَدَهُ فَسَأَلَ عَنْهُ فَقَالَ مَا يَسُرُّكَ أَنْ لاَ تَأْتِيَ بَابًا مِنْ أَبْوَابِ الْجَنَّةِ إِلاَّ وَجَدْتَهُ عِنْدَهُ يَسْعَى يَفْتَحُ لَكَ
