(Imām Bukhārī narrates): Abdullah bin Maslamah narrated to us from Imam Malik from Abi Az-Zinad from Al-A'raj from Hazrat Abu Hurairah (may Allah be pleased with him), he said that

the Messenger of Allah ﷺ mentioned the day of Friday and said: In it there is an hour, such that if a Muslim servant catches that hour while he is standing and praying, and he asks Allah the Exalted for something, then Allah gives him that thing. And he ﷺ indicated with his hand that that hour is very little.
