Silsilah as-Sahihah 2926 — Ten Rewards for Each Letter of the Quran

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever recites a single letter from the Noble Qur'an will receive one good deed, and one good deed is equal to ten like it. I do not say that «الم» is a letter, rather «الف» is a letter, «لام» is a letter, and «ميم» is a letter."
