Ibn ʿUmar said, "When the Prophet ﷺ said, 'The eye sheds tears and the heart feels sorrow.'"
وَقَالَ ابْنُ عُمَرَ ؓ مَا عَنِ النَّبِيِّ ﷺ: «تَدْمَعُ الْعَيْنُ وَيَحْزَنُ الْقَلْبُ».
We went with the Messenger of Allah ﷺ to the blacksmith Abū Sayf, and he was the husband of the wet nurse of Ibrāhīm, peace be upon him, (the son of the Prophet). The Messenger of Allah ﷺ took Ibrāhīm and kissed him and smelled him and later we entered Abū Sayf's house and at that time Ibrāhīm was taking his last breaths, and the eyes of the Messenger of Allah ﷺ started shedding tears.
ʿAbd al-Raḥman b. ʿAwf said, "O Allah's Apostle, even you are weeping!" He said, "O Ibn ʿAwf, this is mercy." Then he wept more and said, "The eyes are shedding tears and the heart is grieved, and we will not say except what pleases our Lord, O Ibrāhīm ! Indeed we are grieved by your separation."
دَخَلْنَا مَعَ رَسُولِ اللَّهِ ﷺ عَلَى أَبِي سَيْفٍ الْقَيْنِ وَكَانَ ظِئْرًا لإِبْرَاهِيمَ عَلَيْهِ السَّلاَمُ فَأَخَذَ رَسُولُ اللَّهِ ﷺ إِبْرَاهِيمَ فَقَبَّلَهُ وَشَمَّهُ ثُمَّ دَخَلْنَا عَلَيْهِ بَعْدَ ذَلِكَ وَإِبْرَاهِيمُ يَجُودُ بِنَفْسِهِ فَجَعَلَتْ عَيْنَا رَسُولِ اللَّهِ ﷺ تَذْرِفَانِ۔
فَقَالَ لَهُ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ ؓ وَأَنْتَ يَا رَسُولَ اللَّهِ؟ فَقَالَ: «يَا ابْنَ عَوْفٍ إِنَّهَا رَحْمَةٌ۔» ثُمَّ أَتْبَعَهَا بِأُخْرَى فَقَالَ ﷺ: «إِنَّ الْعَيْنَ تَدْمَعُ وَالْقَلْبَ يَحْزَنُ، وَلاَ نَقُولُ إِلاَّ مَا يَرْضَى رَبُّنَا۔ وَإِنَّا بِفِرَاقِكَ يَا إِبْرَاهِيمُ لَمَحْزُونُونَ۔»
