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 Some people before you did ask such questions, and on that account lost their faith. 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 they are told to refer to the guidance of God and to the Messenger, they say, "The tradition of our fathers is sufficient for our guidance," even though, in fact, their fathers had neither knowledge nor proper 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 People who Believe! The witnesses between you when death approaches any one of you, at the time of making a will, should be two reliable men from among you, or two from another tribe in case you are travelling in the land and the event of death approaches you; engage them after the prayers, and if you doubt, they must swear by Allah that, “We shall not exchange our oaths for any price even if he is a near relative, nor will we hide the testimony of Allah – if we do, then surely we are of the sinners.” 106 But if it is found that those two were guilty of perjury, let two others stand in their place [who are] foremost [in claim] from those who have a lawful right. And let them swear by Allah, "Our testimony is truer than their testimony, and we have not transgressed. Indeed, we would then be of the wrongdoers." 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
