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 Surely people have asked questions before you, and were then found disbelievers therein. 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 towards what Allah has sent down and towards the Noble Messenger”, they say, “Sufficient for us is what we found our forefathers upon”; even if their forefathers did not have knowledge nor had 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 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 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 Thus it is more likely that they will bear true witness or fear that after their oaths the oaths (of others) will be taken. So be mindful of your duty (to Allah) and hearken. Allah guideth not the froward folk. 108
