يوجد طرق متعددة يمكن بها إثبات ارتكاب الجريمة أمام المحكمة، لكنها مقصورة فقط على ما يمكن أن يحقق اليقين القاطع بالإدانة. فعلى سبيل المثال، إن الأدلة الظرفية مثل بصمات الأصابع على سلاح القتل لا تكفي في ذاتها لإعطاء يقين بنسبة 100% بإدانة صاحب هذه البصمات. ولذلك لا يُقبل هذا النوع من الأدلة وحده في المحكمة الإسلامية. وهناك نوعان من الشهادة يحصل بهما الإثبات القاطع:

There are various ways in which the perpetration of a crime can be proved in court, but these are restricted only to that which can ascertain definite guilt. For example, circumstantial evidence like fingerprints on a murder weapon are not in themselves sufficient to give 100% certainty of the guilt of the owner of the fingerprints. Therefore, this kind of evidence alone is unacceptable in the Islamic court. There are two types of testimony which can confer definite proof :

1) شهادة العيان (الشهادة): إن شهادة من رأى الجريمة وقعت أمام عينيه دليلٌ معتبر. غير أن ذلك لا يُعمل به إلا في الحالات التي تثبت فيها أمانة الشاهد. وثمّة محكمة خاصة غايتها التحقق من حال الشهود الذين يُقدَّمون، من حيث سيرتهم وذاكرتهم وعقلهم وغير ذلك.

1) Eye-Witness Testimony (shahada) : The testimony of someone who has actually seen a crime occurring is a valid evidence. However, this is only applicable in the cases where the trustworthiness of the witness is proven. There is a special court whose purpose is to verify the character, memory, intelligence etc. of any witnesses who are brought forward.

مثالُ ذلك في حالة الزنا، حيث يُشترط شهادةُ أربعةِ شهودٍ عيانٍ لإثبات الجريمة. يقول الله تعالى:

An example of this is in the case of adultery (zina) where the testimony of four eye witnesses are required to prove the crime. Allah (swt) says,.

وَالّٰتِي يَأْتِينَ الْفَاحِشَةَ مِنْ نِسَائِكُمْ فَاسْتَشْهِدُوا عَلَيْهِنَّ أَرْبَعَةً مِنْكُمْ ۖ

“As for those of your women who are guilty of lewdness, call to witness four of you against them.” [TMQ 4:15].

إِذَا لَمْ يَأْتِ أَحَدُ الشُّهُودِ بِشَهَادَةٍ مُعَضِّدَةٍ، أَوْ لَمْ يَسْتَطِعِ الْمُتَّهِمُ بِالْجَرِيمَةِ أَنْ يُحْضِرَ أَرْبَعَةَ شُهُودٍ، فَإِنَّهُ يَخْضَعُ لِعُقُوبَةِ الْقَذْفِ.

If any of the witnesses fails to bring corroborating testimony, or someone who accuses the crime cannot provide four witnesses, then they will be subject to punishment of qadhf (false accusation).

2) الإقرار: اتفق الفقهاء على أن إقرار الجاني كافٍ لثبوت الجريمة، وأنه يجوز إقامة العقوبة المناسبة بناءً على إقراره.

2) Confession (iqrar) : It is agreed that the criminal’s confession is sufficient for the establishment of guilt and that, on the basis of his or her confession, the appropriate punishment can be inflicted.

روى أبو داود أنّ: «امرأةً من غامد جاءت إلى النبي ﷺ فقالت: إني قد زنيتُ، فقال: ارجعي. فرجعت، ثم جاءته من الغد فقالت: لعلك تريد أن تردّني كما رددت ماعز بن مالك؟ فواللهِ إني لحبلى. فقال لها: ارجعي. فرجعت إليه في الغد، فقال: ارجعي حتى تضعي ما في بطنك. فانصرفت. فلما وضعت الولد جاءته بالولد وقالت: هذا قد ولدتُه. فقال: اذهبي فأرضعيه حتى تفطميه. فلما فطمته جاءته بالصبي وفي يده كسرة خبز، فقالت: هذا يا نبي الله قد فطمتُه وقد أكل الطعام. فدفع الصبي إلى رجل من المسلمين، ثم أمر النبي ﷺ فحُفر لها حفرة، وأمر بها فرُجمت. وكان خالد بن الوليد ممن يرجمها، فرمى رأسها بحجر، فتنضّح الدم على وجه خالد فسبّها، فقال النبي ﷺ: مهلاً يا خالد، فوالذي نفسي بيده لقد تابت توبةً لو تابها صاحب مكس لغُفر له. ثم أمر بها فصُلّي عليها ودُفنت».

Abu Daud narrated that : “A woman of Ghamid came to the Prophet (saw) and said, ‘I have committed a punishable sexual act.’ He replied, ‘Go back.’ She then returned and on the next day came to him again and said, ‘Perhaps you want to send me back as you did to Ma‘az ibn Malik. I swear by Allah that I am pregnant.’ He said to her, ‘Go back.’ She returned to him the next day. He said, ‘Go back until you give birth to the child.’ She left. When she gave birth to the child she brought the child to him, and said, ‘Here he is! I have given birth to it.’ He said, ‘Go back and suckle him until you wean him.’ When she had weaned him, she brought the boy to him with something in his hand which he was eating. The boy was then given to a certain man of the Muslims and the Prophet (saw) commanded regarding her. So a pit was dug for her, and he gave orders about her and she was stoned to death. Khalid was one of those who were throwing stones at her. He threw a stone at her. When a drop of her blood fell on his cheek, he abused her. Muhammad (saw) said to him, ‘Gently Khalid. By Him in Whose hand is my soul, she has repented to such an extent that if one who wrongfully takes an extra were to repent to a like extent, he would be forgiven.’ Then giving command regarding her, he prayed over her and she was buried.”.

إلا أنه لو رجع المُقِرُّ عن إقراره، فإنه يُوقَف الحدُّ فوراً، لأنه لم يعد من الممكن إثبات الذنب على وجه اليقين. وكذلك الحكم لو، على سبيل المثال، هرب المُقِرُّ أثناء تنفيذ العقوبة أو شرع في الاحتجاج.

If, however the confessor were to withdraw his or her confession, then the punishment would be stopped immediately, as guilt could no longer be definitely substantiated. This would also be the case if, for example, during the punishment the confessor ran away or began to protest.
