Giving someone a Quran to read is a great form of Sadaqah Jariyah. That means you will get reward for every single letter, word, ayah and surah that is read from your sponsored Quran. And the typical recipients of these Qurans often pass them on to younger generations. Copies donated to mosques are read by multitudes of people over many years. Just imagine receiving continuous reward as long as your sponsored copy of the Quran is read. SubhanAllah!
