She prayed naafil after Fajr and it was said to her that this puts one beyond the pale of Islam
Question

                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 Allah.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 in Saheeh 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. 
In Saheeh 
    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.
