Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: “Whoever stands (in prayer at night) with ten verses will not be written among the heedless; whoever stands with a hundred verses will be written among the devout; and whoever stands with a thousand verses will be written among those who receive heaps of reward.”
