Mukhtasar Bukhari

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) mentioned the day of Friday and said: "There is a moment in it such that if a Muslim servant encounters it while standing and praying, and asks Allah for something, Allah will surely grant him that thing." And the Prophet (peace and blessings of Allah be upon him) indicated with his hand to show the brevity of that moment.
