A daughter of Messenger of Allah ﷺ sent him message while I and Sa'd were with him and I think Ubayy was also there: My son or daughter (the narrator is doubtful) is dying, so come to us. He sent her greeting, saying at the same time: Say! What Allah has been taken belongs to Him, what He has given (belongs to Him), and He has appointed time for everything. She then sent a message adjuring him (to come to her). So he came to her and the child who was on the point of death was placed in the hearts of those whom He wished. Allah shows compassion only to those of His servants who are compassionate.  

أَنَّ ابْنَةً لِرَسُولِ اللَّهِ ﷺ أَرْسَلَتْ إِلَيْهِ وَأَنَا مَعَهُ وَسَعْدٌ وَأَحْسِبُ أُبَيًّا أَنَّ ابْنِي أَوْ بِنْتِي قَدْ حُضِرَ فَاشْهَدْنَا فَأَرْسَلَ يُقْرِئُ السَّلاَمَ فَقَالَ قُلْ لِلَّهِ مَا أَخَذَ وَمَا أَعْطَى وَكُلُّ شَىْءٍ عِنْدَهُ إِلَى أَجَلٍ فَأَرْسَلَتْ تُقْسِمُ عَلَيْهِ فَأَتَاهَا فَوُضِعَ الصَّبِيُّ فِي حِجْرِ رَسُولِ اللَّهِ ﷺ وَنَفْسُهُ تَقَعْقَعُ فَفَاضَتْ عَيْنَا رَسُولِ اللَّهِ ﷺ فَقَالَ لَهُ سَعْدٌ مَا هَذَا قَالَ إِنَّهَا رَحْمَةٌ وَضَعَهَا اللَّهُ فِي قُلُوبِ مَنْ يَشَاءُ وَإِنَّمَا يَرْحَمُ اللَّهُ مِنْ عِبَادِهِ الرُّحَمَاءَ  

The Messenger of Allah ﷺ as saying: A child was born to me at night and I named him Ibrahim after his. He then narrated the rest of the tradition. Anas said: I saw it at the point of the death before the Messenger of Allah ﷺ. Tears began to fall from the eyes of the Messenger of Allah ﷺ. He said: The eye weeps and the heart grieves, but we say only what our Lord is pleased with, and we are grieved for you, Ibrahim.  

قَالَ رَسُولُ اللَّهِ ﷺ وُلِدَ لِيَ اللَّيْلَةَ غُلاَمٌ فَسَمَّيْتُهُ بِاسْمِ أَبِي إِبْرَاهِيمَ فَذَكَرَ الْحَدِيثَ قَالَ أَنَسٌ لَقَدْ رَأَيْتُهُ يَكِيدُ بِنَفْسِهِ بَيْنَ يَدَىْ رَسُولِ اللَّهِ ﷺ فَدَمَعَتْ عَيْنَا رَسُولِ اللَّهِ ﷺ فَقَالَ تَدْمَعُ الْعَيْنُ وَيَحْزَنُ الْقَلْبُ وَلاَ نَقُولُ إِلاَّ مَا يَرْضَى رَبُّنَا إِنَّا بِكَ يَا إِبْرَاهِيمُ لَمَحْزُونُونَ
