Dawud :: Book 6 : Hadith 1393
Narrated Abdullah ibn Amr ibn al-'As:
The Prophet (peace_be_upon_him) said: If anyone prays at night reciting regularly ten verses, he will not be recorded among the negligent; if anyone prays at night and recites a hundred verses, he will be recorded among those who are obedient to Allah; and if anyone prays at night reciting one thousand verses, he will be recorded among those who receive huge rewards.
