In the third verse (94), the address is obviously to the Holy Prophet ﷺ . But, it goes without saying that there is no probability of his doubting the revelation. Therefore, the purpose is to beam the message to the Muslim community through this address where he is not the intended recipient. Then, it is also possible that this address may be to human beings at large asking them if they had any doubts about the Divine revelation sent to them through Sayyidna Muhammad al-Mustafa ﷺ . If they had, let them ask those who recited the Torah and Injil before them. They would tell them that all past prophets and their Books have been announcing the glad tidings of the Last among Prophets. This will remove their scruples and suspicions.
According to Tafsir Mazhari, this verse tells us that anyone in doubt about some religious matter is duty-bound to have his doubts removed by asking genuine ` Ulama' (religious scholars whose learning, honesty and adherence to Qur'an, and Sunnah is well recognized, popularly referred to as ` Ulama' al-Haqq). To continue nursing such doubts is not a good thing to do.
Allah said:
(Those who follow the Messenger, the Prophet who can neither read nor write whom they find written of with them in the Tawrah and the Injil.)(7:157) They are as certain of this as they are about who their children are, yet they hide it and distort it. They did not believe in it despite its clear evidence. Therefore Allah said:
(Truly, those, against whom the Word (wrath) of your Lord has been justified, will not believe. Even if every sign should come to them, until they see the painful torment.) meaning they would not believe in a way that they might benefit from that belief. This is when they believe at a time one may not be able to benefit from his belief. An example is when Musa prayed against Fir`awn and his chiefs, saying:
(Our Lord! Destroy their wealth, and harden their hearts, so that they will not believe until they see the painful torment.)(10:88) And Allah said:
(And even if We had sent down unto them angels, and the dead had spoken unto them, and We had gathered together all things before their very eyes, they would not have believed, unless Allah willed, but most of them behave ignorantly.) (6:111) Allah then said:
