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 nation asked about them before you, and with it they became unbelievers. 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 When it is said to them: "Come to what Allah hath revealed; come to the Messenger": They say: "Enough for us are the ways we found our fathers following." what! even though their fathers were void of knowledge and guidance? 104 O you who believe! take care of your souls; he who errs cannot hurt you when you are on the right way; to Allah is your return, of all (of you), so He will inform you of 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 then, if it is afterwards ascertained that both of them merit (the suspicion of) sin, let two others take their place of those nearly concerned, and let them swear by Allah, (saying): Verily our testimony is truer than their testimony and we have not transgressed (the bounds of duty), for them indeed we should be of the evil-doers. 107 This is more suitable than their bearing testimony as they wish or fear that some oaths may be made void, after their taking oath; so fear Allah and heed the commands; and Allah does not guide the disobedient. 108
