Al-Maaida 5:106

O you who believe, when death approaches one of you, call upon two just Muslim men as witnesses when you make a bequest, or two non-Muslims if you are afflicted with death while you are traveling. But if you have some doubt, keep them both after prayer[71] and let them swear by Allah, “We will not trade our testimony for any price, even in favor of a close relative, nor will we conceal the testimony enjoined by Allah, for then we would surely be among the sinners.”

[71] Prayers are usually attended by a congregation of people.

O you who have believed, testimony [should be taken] among you when death approaches one of you at the time of bequest - [that of] two just men from among you or two others from outside if you are traveling through the land and the disaster of death should strike you. Detain them after the prayer and let them both swear by Allāh if you doubt [their testimony, saying], "We will not exchange it [i.e., our oath] for a price [i.e., worldly gain], even if he should be a near relative, and we will not withhold the testimony of [i.e., ordained by] Allāh. Indeed, we would then be of the sinful."

106. O you who believe! When death approaches any of you, and you make a bequest, (then take) the testimony of two just men of your own folk or two others from outside, while you are travelling through the land and death befalls on you. Detain them both after As-Salât (the prayer), (then) if you are in doubt (about their truthfulness), let them both swear by Allâh (saying): "We wish not for any worldly gain in this, even though he (the beneficiary) be our near relative. We shall not hide Testimony of Allâh, for then indeed we should be of the sinful."

O 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.
