Quran 5, Al-Ma'ida (the Table spread) ⓘ

5:106O ye who believe! Let there be witnesses between you when death draweth nigh unto one of you, at the time of bequest - two witnesses, just men from among you, or two others from another tribe, in case ye are campaigning in the land and the calamity of death befall you. Ye shall empanel them both after the prayer, and, if ye doubt, they shall be made to swear by Allah (saying): We will not take a bribe, even though it were (on behalf of) a near kinsman nor will we hide the testimony of Allah, for then indeed we should be of the sinful.

يَا أَيُّهَا الَّذِينَ آمَنُوا شَهَادَةُ بَيْنِكُمْ إِذَا حَضَرَ أَحَدَكُمُ الْمَوْتُ حِينَ الْوَصِيَّةِ اثْنَانِ ذَوَا عَدْلٍ مِنْكُمْ أَوْ آخَرَانِ مِنْ غَيْرِكُمْ إِنْ أَنْتُمْ ضَرَبْتُمْ فِي الْأَرْضِ فَأَصَابَتْكُمْ مُصِيبَةُ الْمَوْتِ تَحْبِسُونَهُمَا مِنْ بَعْدِ الصَّلَاةِ فَيُقْسِمَانِ بِاللَّهِ إِنِ ارْتَبْتُمْ لَا نَشْتَرِي بِهِ ثَمَنًا وَلَوْ كَانَ ذَا قُرْبَى وَلَا نَكْتُمُ شَهَادَةَ اللَّهِ إِنَّا إِذًا لَمِنَ الْآثِمِينَ
