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
