Quran 2:123

Surah Al-Baqarah. Verse: 123.
The meaning of correct Tilawah.

﴿ ٱلَّذِينَ ءَاتَيۡنَـٰهُمُ ٱلۡكِتَـٰبَ يَتۡلُونَهُ ۥ حَقَّ تِلَاوَتِهِۦۤ ﴾

(Those to whom We gave the Book. Yatlunahu Haqqan Tilawatih.)

' Abu Al-`Aliyah said that Ibn Mas`ud said, "By He in Whose Hand is my soul! The right Tilawah is allowing what it makes lawful, prohibiting what it makes unlawful, reciting it as it was revealed by Allah, not changing the words from their places, and not interpreting it with other than its actual interpretation.''

`Umar bin Al-Khattab said, "They are those who when they recite an Ayah that mentions mercy, they ask Allah for it, and when they recite an Ayah that mentions torment, they seek refuge with Allah from it.'' This meaning was attributed to the Prophet , for when he used to recite an Ayah of mercy, he invoked Allah for mercy, and when he recited an Ayah of torment, he sought refuge from it with Allah.

Allah said in another Ayah,

﴿ قُلۡ ءَامِنُواْ بِهِۦۤ أَوۡ لَا تُؤۡمِنُوٓاْ‌ۚ إِنَّ ٱلَّذِينَ أُوتُواْ ٱلۡعِلۡمَ مِن قَبۡلِهِۦۤ إِذَا يُتۡلَىٰ عَلَيۡہِمۡ يَخِرُّونَ لِلۡأَذۡقَانِ سُجَّدً۬ا • وَيَقُولُونَ سُبۡحَـٰنَ رَبِّنَآ إِن كَانَ وَعۡدُ رَبِّنَا لَمَفۡعُولاً۬ ﴾

(Say (O Muhammad to them): "Believe in it (the Qur'an) or do not believe (in it). Verily, those who were given knowledge before it, when it is recited to them, fall down on their faces in humble prostration. And they say: "Glory be to our Lord! Truly, the promise of our Lord must be fulfilled.'') (17:107-108).
