It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The master of all days is Friday. On it Adam (peace be upon him) was created, on it he was admitted into Paradise, on it he was expelled from it, and the Hour will be established on none other than Friday." This hadith is sahih (authentic) on the condition of Imam Muslim, for he cited Abd al-Rahman bin Abi al-Zinad as a supporting narrator; but the two Shaykhs did not record the words "Sayyid al-ayyam" (the master of days).
