It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Whoever stands (in prayer) with ten verses is not recorded among the heedless; whoever stands with a hundred verses is recorded among the devoutly obedient; and whoever stands with a thousand verses is recorded among the grateful."
