In The Name of Allaah, The Most Merciful, The Bestower of Mercy

Imaam Ibn Katheer [rahimahullaah] stated: Ibn Abee Haatim [rahimahullaah] narrated with his own chain of transmission from Amr Bin Murrah [rahimahullaah], who said: I did not come across an Ayah from the Book of Allaah and did not understand it, except that it grieved me.’ [That] is because I heard the statement of Allaah [The Most High]:

[وَتِلۡكَ ٱلۡأَمۡثَـٰلُ نَضۡرِبُهَا لِلنَّاسِ‌ۖ وَمَا يَعۡقِلُهَآ إِلَّا ٱلۡعَـٰلِمُونَ- And these similitudes We put forward for mankind, but none will understand them except those who have knowledge (of Allah and His Signs, etc.).”[29:43]
