Musannaf Ibn Abi Shayba 22:179

Mu'adh ibn Mu'adh narrated to us, he said: al-Taymi narrated to us, from Abu 'Uthman, from Salman, who said: If a man were to spend the night giving away white singing girls, and another man were to spend the night reciting the Qur'an and remembering Allah, I would consider the one remembering Allah to be better.
