Important Words:
نبتھل (let us pray fervently) is derived from بھل. They say بھله i.e. he left him to his own will; or he left him to himself; he cursed him. ابتھل means, he prayed or supplicated humbly and earnestly and fervently, with energy and effort. باھلهmeans, he cursed him, being also cursed by the latter. مباھلة means, the act of invoking God’s curse on each other, i.e. on whichever party is the wrongdoer (Aqrab & Lane).
انفسنا و انفسکم (our people and your people). The words are the plural of نفس and mean: (1) our souls and your souls; (2) ourselves and yourselves; (3) our people and your people; (4) our co-religionists and your co-religionists (Lane). See also 2:55 and 3:29. Here, as the context shows, the words give the last-mentioned meaning.
Commentary:
The present discussion on Christian doctrines with which this Surah began has been brought to a close in this verse. The reference, as mentioned above, is to the Christian deputation from Najran which consisted of sixty persons and was headed by their chief, ‘Abdul-Masih, known as Al-‘Aqib. They met the Holy Prophet in his Mosque and the discussion on the doctrine of the divinity of Jesus continued at some length. When the question had been fully discussed and the members of the deputation were found to be still insisting on their false doctrine, the Holy Prophet, in obedience to the Divine command contained in the present verse, invited them as a last resort to join him in a sort of prayer contest technically known as مباھلة i.e. invoking the curse of God on the holders of false beliefs. As, however, the Christians did not appear to be sure of their ground, they declined to accept the challenge, thus indirectly admitting the falsity of their doctrine (Zurqani, Khamis & Bayan under 3:3). On this occasion, the Holy Prophet brought out ‘Ali, Fatimah, Hasan and Husain (Khamis & Zurqani) as well as Abu Bakr, ‘Umar, ‘Uthman and others (‘Asakir) in the field and is reported to have said: "If the Christians had accepted the challenge of مباھلة and agreed to pray to God to send His punishment on the lying party, God would have surely destroyed the liars before a year had passed" (Bukhari, Muslim & Tirmidhi).
It may be noted that the prayer contest known as مباھلة is in the nature of seeking God’s arbitration in fundamental religious differences. When other methods of settlement fail, the parties approach Almighty God to decide between them according to His eternal scheme of helping the righteous and destroying the wicked. The act of cursing is thus not in the form of abusing but an earnest supplication to God to uphold the truth and destroy falsehood—to amputate the diseased limb in order to save the healthy one. Thus مباھلةis a very serious affair and should be resorted to in very rare cases, subject to the following conditions, which are deducible from the present verse as well as from the relevant sayings of the Holy Prophet; (1) the point in dispute should be a matter of supreme and fundamental religious importance and should be based on clear scriptural authority; (2) the matter should first be fully argued and discussed between the parties; (3) the مباھلة should take place only if and when after the aforesaid discussion each party still continues to adhere to its views, definitely holding the other party to be in the wrong; (4) for the actual contest the parties should assemble in a suitable place together with the members of their families and a suitable number of others holding similar views, and there solemnly invoke the curse of God on the party sticking to falsehood.
As to the form or time of punishment which, as a result of مباھلة must overtake the offending party, the verse sheds no light. The matter rests entirely with God. From the above-quoted tradition, however, it may be deduced that if any period at all is to be fixed, it should be not less than a year. But the form of punishment must still rest on Divine will. The Judge in heaven reserves the right of deciding each individual case as He thinks fit. The result is left to speak for itself.
It may be noted here incidentally that during the discussions with the Christian deputation from Najran, the Holy Prophet allowed them to pray in his Mosque in their own way, which they did facing the east—an act of religious toleration unparalleled in the history of all religion (Zurqani).
