Sins have many side-effects. One of them is that they steal knowledge from you.
Ibn Qayyim Al-JawziyyaWhoever mocks his brother for a sin they repented from will not die till he himself falls into the same sin.
Ibn Qayyim Al-JawziyyaThe heart will rest and feel relief if it is settled with Allah. And it will worry and feel anxious if it is settled with the people.
Ibn Qayyim Al-JawziyyaIf you wish to check how much you love Allah, then see how much your heart loves the Quran, and you will know the answer.
