Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, these hearts become rusty just as iron becomes rusty." It was asked: O Messenger of Allah! What is its polish (means of shining)? He said: "Remembering death in abundance and recitation of the Qur'an."
