SADAQAH JARIYAH
When you share Islamic knowledge, every person who learns — and every person who learns from them — adds to your reward. This is the beautiful mathematics of ongoing charity.
مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتْ سَبْعَ سَنَابِلَ فِى كُلِّ سُنۢبُلَةٍ مِّائَةُ حَبَّةٍ
The example of those who spend their wealth in the cause of Allah is that of a grain which sprouts seven ears, in every ear a hundred grains.
Surah Al-Baqarah 2:261
Each node represents a unique reader. Active readers pulse with light.
إِذَا مَاتَ الإِنْسَانُ انْقَطَعَ عَنْهُ عَمَلُهُ إِلاَّ مِنْ ثَلاَثَةٍ إِلاَّ مِنْ صَدَقَةٍ جَارِيَةٍ أَوْ عِلْمٍ يُنْتَفَعُ بِهِ أَوْ وَلَدٍ صَالِحٍ يَدْعُو لَهُ
When a person dies, their deeds come to an end except for three: ongoing charity (sadaqah jariyah), knowledge from which benefit is gained, or a righteous child who prays for them.
Sahih Muslim 1631
Sadaqah jariyah is charity that continues to give reward even after it has been given. Sharing Islamic knowledge is one of its most powerful forms — every person who learns and acts upon it adds to your continuous stream of reward, even beyond your lifetime.
