*8) Most of the commentators have expressed the view that this verse was sent down concerning Walid bin 'Uqbah bin Abi Mu'ait. Its background is this: When the tribe of the Bani al-Mustaliq embraced Islam, the Holy Prophet sent Walid bin `Uqbah to collect the zakat from them. When he arrived in their territory, he became scared due to some reason and without visiting the people of the tribe returned to Madinah and complained to the Holy Prophet that they had refused to pay the zakat and had even wanted to kill him. On hearing this the Holy Prophet became very angry and he made up his mind to dispatch a contingent to punish those people. According to Borne traditions he had despatched the contingent, and according to others, he was about to despatch it. In any case aII agree that in the meantime the chiefof the Bani al-Mustaliq, Harith bin Dirar (father of Juwairiyah, wife of the Holy Prophet), arrived at the head of a deputation, and submitted: "By God, we did not at alI see Walid; therefore, there could be no question of refusing to pay the zakat and wanting to kill him. We arc steadfast to the Faith and have no intention to withhold the zakat. " At this, this verse was sent down. With a little variation in wording this incident has been related by Imam Ahmad, Abi Hatim, Tabarani, and Ibn Jarir, on the authority of Hadrat 'Abdullah bin 'Abbas, Harith bin Dirar, Mujahid, Qatadah, 'Abdur Rehman bin Abi Laila, Yazid bin Ruman, Dahhak and Muqatil bin Hayyan. In the tradition reported by Hadrat Umm Salamah this whole story has been related likewise but there is no reference to the name of Walid.
On this critical occasion when on account of believing in a baseless report a grave blunder was about to be committed, AIIah gave the Muslims this guiding principle to be followed on receipt of news: 'Whenever you receive important news bearing upon a vital matter, you should not accept it immediately but should first examine the man who has brought it. If he is an evil man whose report they not be authentic normally, you should inquire into it carefully to ascertain the truth instead of accepting it and ecting on it immediately." From this Divine Command An important legal principle is deduced, the sphere of application of which is very vast. According to it, it is not permissible for a Muslim government to take any action against a person or a group or a nation on the basis of the reports provided by the secret agents whose character might be doubtful. On the basis of this very principle the traditionists introduced the art of critical appraisal in the science of Hadith in order to determine the value and worth of the people through whom traditions of the Holy Prophet reached the later generations, and the jurists established this principle in the law of evidence that in a matter from which a Shari'ah value can be deduced, or a duty imposed on a person; the evidence of an evil man would be unacceptable. However, all scholars agree that as far as the common worldly matters are concerned it is not necessary to ascertain the truth of every news and the reliability of every informer. For the word used in the verse is naba'. which dces not apply to every news but only to the news of consequence. That is why the jurists say that this principle does not apply in the case of ordinary matters. For example, if a person goes to visit somebody and seeks permission to enter the house, and a person comes out and conveys the permission, he can enter the house accordingly no matter whether the one conveying the permission from the master of the house was good or bad. Likewise, the scholars are also agreed that the evidence, as well as the report, of the people whose evil does not relate to lying and immorality, but they are regarded as unrighteous only on account of false beliefs, will also be acceptable. Only the falsehood of heir creed cannot be a hindrance to accepting their evidence or reports.
