Ma'arif al-Qur'an
Mufti Muhammad Shafiأَمْ حَسِبَ الَّذِينَ فِي قُلُوبِهِم مَّرَضٌ أَن لَّن يُخْرِجَ اللَّـهُ أَضْغَانَهُمْ (Do those having disease in their hearts rather think that Allah will never expose their grudges [ against Islam ]? - 47:29) " The word adghan is the plural of dighn which means secret enmity, rancour, malice or spite. This verse was revealed in connection with hypocrites to expose their bitter hatred and rancour against Islam which they were hiding in their hearts. Outwardly, they expressed their love for the Holy Prophet ﷺ and inwardly they harbored violent hatred and enmity for him. They knew that Allah is the knower of the unseen, yet they were not concerned that He would expose their inner secret and covert enmity to the people. Ibn Kathir says in Surah Bara'ah that Allah has described their works, actions and activities which expose their hypocrisy and they would be identified as hypocrites. Therefore, another name of that Surah is fadihah meaning exposing to shame or disgrace, because specific qualities of the hypocrites are set out in it.
