Believers, do not ask questions about things which, if they were made known to you, would only become burdensome for you; but if you ask them when the Quran is being revealed, they shall be made plain to you -- God has kept silent about them: God is most 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 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 believers, look after your own souls. He who is astray cannot hurt you, if you are rightly guided. Unto God shall you return, all together, and He will tell you what you were doing. 105 O you who believe, let two honest men among you be witness when you dictate your last will and testament as (the hour of) death draws near; and if death approaches while you are on a journey, two men other than yours. Detain them after the service of prayer, and if you doubt their word make them swear by God that: "We shall not take a bribe even though it be offered by a near relative, nor hide the testimony of God, for then we shall surely be sinful." 106 If their honesty is challenged, two others from the relatives of the deceased should swear in the same way and testify to the bequest saying, "We swear by God that our testimony is the true one. We do not transgress in the matter lest we become unjust ones." 107 It is thus likely that men will bear witness rightly, or else fear that their oaths may be disproved by oaths given after them. So fear God, and do not forget that God does not guide the iniquitous. 108
