Halocho #1885 - May one say Tehillim by heart?

The תּוֹרָה is divided into two parts: תּוֹרָה שֶׁבִּכְתָב, the written-law (תנ"ך) and  תּוֹרָה שֶׁבְּעַל פֶּה, the oral-law (Mishna and Gemara).

Even if one knows parts of תּוֹרָה שֶׁבִּכְתָב by heart, one should be careful not say them without a text.

The exception being those verses that everybody knows by heart like those תְּהִלִּים said often during prayers like אַשְׁרֵי.

If possible, one should pray from a סִדּוּר, since Davening includes many verses that not everybody knows by heart.

Blind people are allowed to say everything by heart.

מִזְמוֹרֵי תְהִלִּים וְכֵן שְׁאָר פָּרָשִׁיּוֹת מִתּוֹרָה נְבִיאִים וּכְתוּבִים שֶׁאֵינָם שְׁגוּרִים בְּפִי הַכֹּל, אָסוּר לְאָמְרָם בְּעַל פֶּה

 אֲפִלּוּ מִי שֶׁהוּא יוֹדֵעַ לְאָמְרָם בְּעַל פֶּה, יֶשׁ לוֹ לִזָּהֵר שֶׁלֹּא לְאָמְרָם בְּעַל פֶּה. וְסוּמָא מֻתָּר
