ما هو الدليل الذي يفرق بين "قول القلب" و "عمل القلب" فيما يتعلق بالأعمال القلبية، ويترتب عليه حكم؟

Faith encompasses the utterance of the tongue (the testimony of Tawhid) and the utterance of the heart (certainty, affirmation, and belief). It also includes the actions of the heart (sincerity, love of Allah, and fear of Him) and the actions of the limbs. This is indicated by the Hadith of Abu Hurairah in Sahih Muslim: "Whoever you meet behind this wall testifying that there is no deity worthy of worship but Allah, with his heart certain of it, then give him glad tidings of Paradise." Furthermore, the disbelief of the hypocrites was due to their hearts not affirming belief. The actions of the heart are also indicated by Allah’s saying: "Indeed, the believers are those who, when Allah is mentioned, their hearts tremble" and "so their hearts humble themselves to Him" and "and came with a repenting heart."
