O ye who believe! Ask not questions about things which, if made plain to you, may cause you trouble. But if ye ask about things when the Qur'an is being revealed, they will be made plain to you, Allah will forgive those: for Allah is Oft-forgiving, Most Forbearing. 101 A people asked such [questions] before you; then they became thereby disbelievers. 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 And when it is said to them, 'Come now to what God has sent down, and the Messenger, they say, 'Enough for us is what we found our fathers doing.' What, even if their fathers had knowledge of naught and were not guided? 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 you who believe! call to witness between you when death draws nigh to one of you, at the time of making the will, two just persons from among you, or two others from among others than you, if you are travelling in the land and the calamity of death befalls you; the two (witnesses) you should detain after the prayer; then if you doubt (them), they shall both swear by Allah, (saying): We will not take for it a price, though there be a relative, and we will not hide the testimony of Allah for then certainly we should be among the sinners. 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 is more likely that they will give testimony according to its [true] objective, or [at least] they would fear that [other] oaths might be taken after their oaths. And fear Allah and listen; and Allah does not guide the defiantly disobedient people. 108
