Dought & clear, - She prayed naafil after Fajr and it was said to her that this puts one beyond the pale of Islam.

I often used to pray half an hour after Fajr prayer, after reading
Qur'aan, feeling that I wanted to pray to Allaah. But I got a shock
when I was talking to my friend and she said that it is not
permissible to pray after Fajr and that this puts one beyond the pale
of Islam. Is this true? How can that be when I am praying to Allaah?
Please explain that to me.
Praise be to Allaah.
Firstly:
One of the greatest acts of worship that a Muslim can do and draw
close to Allaah is prayer. The Prophet(peace and blessings of Allaah
be upon him) said: "Prayer is the best thing prescribed, so whoever
can do a great deal of it, let him do that." Narrated by al-Tabaraani
and classed as hasan by al-Albaani inSaheeh al-Jaami'(3870).
But the Prophet(peace and blessings of Allaah be upon him) forbade us
to offer naafil prayers at certain times. For more details please see
the answer to question no. 20013.
These times include the period from after Fajr prayer until the sun
has risen and become high, which is until approximately fifteen
minutes after sunrise.
InSaheeh Muslim(832) it is narrated that the Prophet(peace and
blessings of Allaah be upon him) said to 'Amr ibn 'Abasah (may Allaah
be pleased with him): "Pray Fajr, then refrain from praying until the
sun has risen and become high". The prayer that is forbidden at these
times is naafil prayer for which there is no reason, which the
scholars call al-nafl al-mutlaq (general naafil prayer), such as that
which is mentioned in the question, where a person stands and offers a
voluntary prayer to Allaah after Fajr. This kind of prayer is
disallowed (at this time).
As for prayers for which there is a reason, such as greeting the
mosque, the Sunnah prayer after wudoo', two rak'ahs following tawaaf
and so on, these may be done when the reason for them is present, even
if that is at a time when other naafil prayers are forbidden. See the
answer to question no. 306.
Secondly:
As for your friend's saying that praying at this time puts one beyond
the pale of Islam, this is not correct, and it is speaking about
Allaah without knowledge. It is not permissible for anyone to say
anything about the religion of Allaah that he does not know. Allaah
says (interpretation of the meaning):
"Say (O Muhammad): (But) the things that my Lord has indeed forbidden
are Al-Fawaahish (great evil sins and every kind of unlawful sexual
intercourse) whether committed openly or secretly, sins (of all
kinds), unrighteous oppression, joining partners (in worship) with
Allaah for which He has given no authority, and saying things about
Allaah of which you have no knowledge"
[al-A'raaf 7:33]
So she has to repent to Allaah.
Offering naafil prayers at this time is not allowed, and the one who
does that is sinning, because he is doing something that the
Prophet(peace and blessings of Allaah be upon him) forbade, but that
is not kufr as your friend claims.
And Allaah knows best.
