Three deeds that outlive you
إِذَا مَاتَ ابْنُ آدَمَ انْقَطَعَ عَنْهُ عَمَلُهُ إِلَّا مِنْ ثَلَاثٍ: صَدَقَةٍ جَارِيَةٍ، أَوْ عِلْمٍ يُنْتَفَعُ بِهِ، أَوْ وَلَدٍ صَالِحٍ يَدْعُو لَهُ
Idha mata-bnu Adama-nqata'a anhu amaluhu illa min thalath: sadaqatin jariyah, aw ilmin yuntafa'u bih, aw waladin salihin yad'u lah.
"When the son of Adam dies, his deeds come to an end except for three: an ongoing charity, knowledge people benefit from, and a righteous child who supplicates for him."
Narrated by Abu Hurayrah. Sahih Muslim 1631
A short reflection
The three things still earning while you sleep, and after you stop. A water pump, a book, a praying child. Plant at least one.
