Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:
إِنَّ مِمَّا يَلْحَقُ الْمُؤْمِنَ مِنْ عَمَلِهِ وَحَسَنَاتِهِ بَعْدَ مَوْتِهِ عِلْمًا عَلَّمَهُ وَنَشَرَهُ وَوَلَدًا صَالِحًا تَرَكَهُ وَمُصْحَفًا وَرَّثَهُ أَوْ مَسْجِدًا بَنَاهُ أَوْ بَيْتًا لِابْنِ السَّبِيلِ بَنَاهُ أَوْ نَهْرًا أَجْرَاهُ أَوْ صَدَقَةً أَخْرَجَهَا مِنْ مَالِهِ فِي صِحَّتِهِ وَحَيَاتِهِ يَلْحَقُهُ مِنْ بَعْدِ مَوْتِهِ
Verily, among the good deeds that will join a believer after his death are these: knowledge which he taught and spread, a righteous child he leaves behind, a copy of the Quran he leaves for inheritance, a mosque he has built, a house he built for travelers, a well he has dug, and charity distributed from his wealth while he was alive and well. These deeds will join him after his death.
