If they served Allah in truth and sincerity according to the knowledge they had, and didn't reject any of the messengers and didn't purposefully "turn a blind eye" to the messages of Allah and to the messengers, they would have been muslims.
I find the events surrounding joan of arc (the jihadi) and subsequent court trials to be very intriguing despite the level of knowledge that she appeared to be upon and feel that Allah was organizing events in a subtle way based upon circumstances and sincerity with a master plan in place.

The trial for*heresy*was politically motivated. The tribunal was composed entirely of pro-English and Burgundian clerics, and overseen by English commanders including the Duke of Bedford and the Earl of Warwick.[63]Legal proceedings commenced on 9 January 1431 at*Rouen, the seat of the English occupation government.[64]*The procedure was suspect on a number of points, which would later provoke criticism of the tribunal by the chief inquisitor who investigated the trial after the war.[65]Under ecclesiastical law, Bishop Cauchon lacked*jurisdiction*over the case.
Cauchon owed his appointment to his partisan support of the English government, which financed the trial. The low standard of evidence used in the trial also violated inquisitorial rules.
Clerical notary Nicolas Bailly, who was commissioned to collect testimony against Joan, could find no adverse evidence.
Without such evidence the court lacked grounds to initiate a trial.
Opening a trial anyway, the court also violated ecclesiastical law by denying Joan the right to a legal adviser.
In addition, stacking the tribunal entirely with pro-English clergy violated the medieval Church's requirement that heresy trials be judged by an impartial or balanced group of clerics.
Upon the opening of the first public examination, Joan complained that those present were all partisans against her and asked for "ecclesiastics of the French side" to be invited in order to provide balance. This request was denied.
The trial record contains statements from Joan that the eyewitnesses later said astonished the court, since she was an illiterate peasant and yet was able to evade the theological pitfalls the tribunal had set up to entrap her. The transcript's most famous exchange is an exercise in subtlety:
"Asked if she knew she was in God's grace, she answered, 'If I am not, may God put me there; and if I am, may God so keep me.'"
The question is a scholarly trap. Church doctrine held that no one could be certain of being in God's grace.
If she had answered yes, then she would have been charged with heresy. If she had answered no, then she would have confessed her own guilt.
The court notary Boisguillaume later testified that at the moment the court heard her reply, "Those who were interrogating her were stupefied."

The circumstances surrounding the kangaroo trial constantly bring our illuminated sister Aafia Siddiqui to my mind.

Explaining why the US may have chosen to charge her as they did, rather than for her alleged terrorism,*Bruce Hoffman, professor of security studies at Georgetown University, said:*There’s no intelligence data that needs to be introduced, no sources and methods that need to be risked. It’s a good old-fashioned crime; it's the equivalent of a 1920s gangster with a tommy gun.
A lawyer for Siddiqui, Elaine Whitfield Sharp, expressed scepticism regarding both terrorism and assault charges:*I think it's interesting that they make all these allegations about the dirty bombs and other items she supposedly had, but they haven't charged her with anything relating to terrorism... I would urge people to consider her as innocent unless the government proves otherwise.
A three-person defence team was hired by the Pakistani embassy to supplement her two existing public defenders, but Siddiqui refused to co-operate with them.
She tried to dismiss her lawyers because they were Jewish.
She said the case against her was a Jewish conspiracy, and demanded that no Jews be allowed on the jury.
She demanded that all prospective jurors be*DNA-tested, and excluded from the jury at her trial "if they have a*Zionist*or Israeli background ... they are all mad at me ... I have a feeling everyone here is them—subject to genetic testing. They should be excluded, if you want to be fair."
Siddiqui's legal team said, in regard to her comments, that her incarceration had damaged her mind.
Prior to her trial, Siddiqui said she was innocent of all charges. She maintained she could prove she was innocent, but refused to do so in court.
On 11 January 2010, Siddiqui told the Judge that she would not co-operate with her attorneys, and wanted to fire them. She said she did not trust the Judge, and added, "I'm boycotting the trial, just to let all of you know. There's too many injustices." She then put her head down on the defence table as the prosecution proceeded.

With all that said, those who live and die know what they know of their circumstances and situation and Allah knows the depths of their circumstances, situations, intentions and deeds, we would do well to consider the guidance we have received and humble ourselves before the Creator and Master of the universe who has no ascendant, descendent, partner, counterpart or demi-counterpart and to whom all things return.
