Whoever recites a letter from the Book of Allah will be credited with a good deed for it, and a good deed is multiplied tenfold

The Prophet (may Allah's peace and blessings be upon him) informed that any Muslim who recites one letter from the Book of Allah will be credited with a good deed for it, and the reward gets multiplied for him up to tenfold. To illustrate this, he said: "I am not saying that 'Alif-Lām-Mīm' is one letter, but Alif is a letter, Lām is a letter, and Mīm is a letter." Thus, they are three and equal thirty good deeds.
