Mukhtasar Muslim

Abu Huraira (may Allah be pleased with him) reports that Abul Qasim (peace and blessings of Allah be upon him) said: "There is an hour on Friday during which, if a Muslim stands in prayer and asks Allah for something good, Allah will surely grant it to him." And (the narrator said) that the Prophet (peace and blessings of Allah be upon him) indicated with his hand that it is very brief, and he encouraged seeking it.
