Musannaf Ibn Abi Shayba 21:351

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