Sura al-Māʾidah 5:106

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ شَهَٰدَةُ بَيْنِكُمْ إِذَا حَضَرَ أَحَدَكُمُ ٱلْمَوْتُ حِينَ ٱلْوَصِيَّةِ ٱثْنَانِ ذَوَا عَدْلٍ مِّنكُمْ أَوْ ءَاخَرَانِ مِنْ غَيْرِكُمْ إِنْ أَنتُمْ ضَرَبْتُمْ فِى ٱلْأَرْضِ فَأَصَٰبَتْكُم مُّصِيبَةُ ٱلْمَوْتِ تَحْبِسُونَهُمَا مِنۢ بَعْدِ ٱلصَّلَوٰةِ فَيُقْسِمَانِ بِٱللَّـهِ إِنِ ٱرْتَبْتُمْ لَا نَشْتَرِى بِهِۦ ثَمَنًا وَلَوْ كَانَ ذَا قُرْبَىٰ وَلَا نَكْتُمُ شَهَٰدَةَ ٱللَّـهِ إِنَّآ إِذًا لَّمِنَ ٱلْأَثِمِينَ

O ye who believe! When death approaches any of you, (take) witnesses among yourselves when making bequests,- two just men of your own (brotherhood) or others from outside if ye are journeying through the earth, and the chance of death befalls you (thus). If ye doubt (their truth), detain them both after prayer, and let them both swear by Allah: "We wish not in this for any worldly gain, even though the (beneficiary) be our near relation: we shall hide not the evidence before Allah: if we do, then behold! the sin be upon us!"
