(regarding the Verse):-- 'Neither say your prayer aloud, nor say it in a low tone.' (17.110) This Verse
was revealed while Allah's Messenger (ﷺ) was hiding himself in Mecca, and when he raised his voice while
reciting the Quran, the pagans would hear him and abuse the Quran and its Revealer and to the one
who brought it. So Allah said:--
'Neither say your prayer aloud, nor say it in a low tone.' (17.110) That is, 'Do not say your prayer so
loudly that the pagans can hear you, nor say it in such a low tone that your companions do not hear
you.' But seek a middle course between those (extremes), i.e., let your companions hear, but do not
relate the Quran loudly, so that they may learn it from you.
Sahih al-Bukhari Book 97, Hadith 116
“I heard the Messenger of Allah (ﷺ)
say:
‘That which is lawful is plain and that which is unlawful is
plain,
and between them are matters that are not clear, about which
not many
people know. Thus he who guards against the unclear matters,
he clears
himself with regard to his religion and his honor. But he
who falls
into the unclear matters, he falls into that which is
unlawful. Like
the shepherd who pastures around a sanctuary, all but
grazing therein.
Every king has a sanctuary. And beware! Allah’s
sanctuary is His
prohibitions. Beware! In the body there is a piece
of flesh which, if
it is sound, the whole body will be sound, and if
it is corrupt, the
whole body will be corrupt. It is the heart.’”
Sunan Ibn Majah Book 36, Hadith 59
Yahya related to me from Malik from Yahya ibn Said from Muhammad
ibn Ibrahim ibn al-Harith at-Taymi from Abu Salama ibn Abd ar Rahman
that Abu Said said that he had heard the Messenger of Allah, may Allah
bless him and grant him peace, say, "A group of people will appear
among you whose prayer, fasting and deeds will make you think little
of your own prayer, fasting and deeds. They will recite the Quran,
but it wil not get past their throats, and they will pass through the
deen like an arrow passes through game. You look at the arrowhead, and
you see nothing, and you look at the shaft, and you see nothing, and
you look at the flights, and you see nothing. And you are in doubt
about the notch."
Muwatta Malik Book 15, Hadith 11
