1. Creations around you
2. History, past happenings that we can learn from. Either follow or avoid
3. Revelation from Allah (Quran)
Children learn mainly from things around them.
Schoolchildren learn from history subject(which is a very important subject)
Believers learn from revelation from Quran.
It is very important that as Believers, we MUST learn the Quran in order to complete the learning areas.
Ya Rabb, help us learn your deen Ya Allah. Make us among the people of tawqa and with knowledge.
