Jihad (Kitab Al-Jihad)
Dawud :: Book 14 : Hadith 2769
Narrated Sa'd ibn AbuWaqqas:
We went out with the Apostle of Allah (peace_be_upon_him) from Mecca making for Medina. When we were near Azwara', he alighted, then raised his hands, and made supplication to Allah for a time, after which he prostrated himself, remaining a long time in prostration. Then he stood up and raised his hands for a time, after which he prostrated himself, remaining a long time in prostration.
He then stood up and raised his hands for a time, after which he prostrated himself. Ahmad mentioned it three times.
He then said: I begged my Lord and made intercession for my people, and He gave me a third of my people, so I prostrated myself in gratitude to my Lord. Then I raised my head and begged my Lord for my people, and He gave me a third of my people, so I prostrated myself in gratitude to my Lord. Then I raised my head and begged my Lord for my people and He gave me the remaining third, so I prostrated myself in gratitude to my Lord.
