It is narrated from Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) that once Sayyiduna Umar (may Allah be pleased with him) while delivering a sermon said: "Be aware! Some people say, 'What is the meaning of rajm (stoning)?' In the Noble Qur'an, there is only mention of flogging, whereas the punishment of rajm was given by the Prophet (peace and blessings be upon him) himself, and we have also given it. If people did not say that Umar has added to the Qur'an, I would have written it in the Qur'an."
