Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said after stoning the Aslami: "Avoid this evil deed, Allah Almighty has forbidden it. Whoever commits it and Allah covers him, he should also conceal his sin, because whoever reveals his secret, we will enforce the Book of Allah (its rulings) upon him."
