Difficulty in Understanding the Qur’an

We can understand the Qur'an by reading the commentary on it.   There are general verses and specific verses, so be careful how to understand the Quran. “In the Quran there are foundation/principles (mother of the Book) and there are verses which are ambiguous..”Surah Ale Imran, verse 7 The Ahlulbayt are “those pegged in knowledge.”
