What did Prophet Muhammad (saw) tell people about the night of Al-Qadr? (Hadith of 'Ubada bin As-Samit: Narrated 'Ubada bin As-Samit)
 Narrated 'Ubada bin As-Samit:                           "Allah's Apostle went out to inform the people about the (date of the)     night of decree (Al-Qadr) but there happened a quarrel between two      Muslim men. The Prophet said, "I came out to inform you about (the      date of) the night of Al-Qadr, but as so and so and so and so      quarrelled, its knowledge was taken away (I forgot it) and maybe it      was better for you. Now look for it in the 7th, the 9th and the 5th      (of the last 10 nights of the month of Ramadan)."
