It is narrated from Sayyiduna al-Husayn bin Ali (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him), to test Ibn Sa'id, concealed "smoke" (dukhan) in his heart. Then he (peace and blessings be upon him) asked him: What have I hidden for you? He (giving an incomplete word with the help of devils) said: "Dukh." So he (peace and blessings be upon him) said to him: "Be gone in disgrace! You will never go beyond your capacity and your station." Then, when he turned his back and left, the Prophet (peace and blessings be upon him) asked the Companions: "What did he say?" Some submitted that he had said "Dukh", and some said that he had said "Dikh". Then the Prophet (peace and blessings be upon him) said: "You are already differing among yourselves while I am present among you; after me your differences will be far more severe than this."
The chain of this hadith is hasan (good). Imam Ishaq bin Rahwayh narrated it in his Musnad, and the basis of this incident is also found in Sahih al-Bukhari and Sahih Muslim.
