In this treatise you will find Ibn Rajab's in-depth explanation of the following hadeeth:

Narrated Anas bin Malik:

Allah's Messenger (ﷺ) said,

يَتْبَعُ الْمَيِّتَ ثَلاَثَةٌ، فَيَرْجِعُ اثْنَانِ وَيَبْقَى مَعَهُ وَاحِدٌ، يَتْبَعُهُ أَهْلُهُ وَمَالُهُ وَعَمَلُهُ، فَيَرْجِعُ أَهْلُهُ وَمَالُهُ، وَيَبْقَى عَمَلُهُ

When carried to his grave, a dead person is followed by three, two of which return (after his burial) and one remains with him: his relative, his property, and his deeds follow him; relatives and his property go back while his deeds remain with him. [Sahih al-Bukhari: 6514]
