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
