O believers, do not ask about things which, if made known to you, may vex you. But if you ask about them when the Qur'an is being revealed they will be unfolded to you. God has overlooked (your failings) in this (respect), for God is forgiving and forbearing. 101 A people before you indeed asked such questions, and then became disbelievers on account of them. 102 IT IS NOT of God's ordaining that certain kinds of cattle should be marked out by superstition and set aside from the use of man; yet those who are bent on denying the truth attribute their own lying inventions to God. And most of them never use their reason: 103 for when they are told, "Come unto that which God has bestowed from on high, and unto the Apostle" - they answer, "Enough for us is that which we found our forefathers believing in and doing." Why, even though their forefathers knew nothing, and were devoid of all guidance? 104 Believers! Take heed of your own selves. If you are rightly guided, the error of he who strays will not harm you. To Allah will all of you return; then He will let all of you know what you did. 105 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!" 106 But if afterwards it should come to light that the two [witnesses] have become guilty of [this very] sin, then two others - from among those whom the two former have deprived of their right - shall take their place and shall swear by God, "Our testimony is indeed truer than the testimony of these two, and we have not transgressed the bounds of what is right - or else, may we indeed be counted among the evildoers!" 107 That shall make it more likely that they shall produce the testimony according to the fact thereof or they shall fear that other oaths would be admitted after their oaths. And fear Allah and hearken; and Allah guideth not a transgressing people. 108
