Sayyiduna Mutarrif narrates from his father (Abdullah bin al-Shikhkhir) that the Prophet (peace and blessings be upon him) said: "Whoever fasts perpetually (that is, keeps fasting all year without a break) has neither fasted nor broken his fast," or (he said): "Neither has his fast counted nor his breaking of it." This hadith is sahih (authentic) on the condition of the two Shaykhs. It also has an authentic supporting narration (shahid) on their condition, which they did not record:

It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that it was said to the Messenger of Allah (peace and blessings be upon him): So-and-so fasts every day perpetually (never missing a day). He (peace and blessings be upon him) said: "He has neither fasted nor broken his fast."
