Give the World for Islamic Knowledge
It is reported that Imām Al-Ḥasan Al-Baṣrī – Allāh have mercy on him – said: To learn a single topic of knowledge and teach it to a Muslim is more beloved to me than having the whole world and giving it in the cause of Allāh. Al-Khaṭīb Al-Baghdādī, Al-Faqīh wa Al-Mutafaqqih article 53.
