Abbas - Tanwîr al-Miqbâs min Tafsîr Ibn ‘Abbâs
(Again, We gave the Scripture) the Torah (unto Moses, complete) with commands and prohibitions, promises and threats, reward and punishment (for him who would do good) for him who is in a good state; it is also said that this means: for him who follows the excellence of Moses and the conveyance of the message of his Lord, (an explanation of all things) He says: it is an exposition of all things regarding the lawful and the unlawful, (a guidance) from error (and a mercy) that absolves the one who believes in Allah from His torment, (that they might believe in the meeting with their Lord) that they might believe in resurrection after death.
Then (thumma is for [describing events in a] sequence) We gave Moses the Scripture, the Torah, complete, in grace, for him who does good, by observing it, and a detailing, an explanation, of all things, needed for religion, and as a guidance and a mercy, that perhaps they, that is, the Children of Israel, might believe in the encounter with their Lord, through the Resurrection.
Then We gave Moses the Scripture: that is to say, after He charged you with wayfaring along the path of virtue in ancient times, We gave Moses the scripture, complete for him who does good, that is, to consummate the nobleness of sanctity and the grace of prophethood over and above the virtuousness of Moses in his wayfaring along the path of perfection and the station he attained of communion [with God] and proximity [to Him] by means of the existence divinely-endowed after the annihilation in the unity, as God says and when he recovered his senses he said, 'Glory be to You! I repent to You and I am the first of those who believe' [Q. 7:143], in perfection and in [the necessity of] calling creatures to the Truth, and a detailing of all things, which creatures will need for the final return, and as a guidance, for them to their Lord in wayfaring along His path, and a mercy, to them, in effusing unto them His perfections by means of Moses and the scripture given to him, that perhaps they might believe in the encounter with their Lord, with either cognitive faith or that [faith] of presential vision.
("Did they not disbelieve in that which was given to Musa of old" They say: "Two kinds of magic the Tawrah and the Qur'an, each helping the other!" And they say: "Verily, in both we are disbelievers.") 28:48 Allah said about the Jinns that they said,
("O our people! Verily, we have heard a Book sent down after Musa, confirming what came before it, it guides to the truth.") 46:30 Allah's statement,
تَمَامًا عَلَى الَّذِى أَحْسَنَ وَتَفْصِيلاً
(...complete for that which is best, and explaining all things in detail...") means; `We made the Book that We revealed to Musa, a complete and comprehensive Book, sufficient for what he needs to complete his Law.' Similarly, Allah said in another Ayah,
(...that they might believe in the meeting with their Lord. And this is a blessed Book (the Qur'an) which We have sent down, so follow it and have Taqwa so that you may receive mercy.) This calls to following the Qur'an. Allah encourages His servants to follow His Book (the Qur'an) and orders them to understand it, adhere to it and call to it. He also describes it as being blessed, for those who follow and implement it in this life and the Hereafter, because it is the Firm Rope of Allah.
Maududi - Sayyid Abul Ala Maududi - Tafhim al-Qur'an
"..... to believe in meeting with one's Lord" means that one should believe that one shall have to render an account of one's deeds to one's Lord; therefore one should live a life of responsibility. Here it may imply that the Torah was sent (1) to produce a sense of responsibility among the Israelites themselves and (2) to induce the other people to make a study of its high moral system of life, and to observe the noble effects of its guidance and blessing on those who adopted its teachings so that they may be convinced that a life of responsibility based on the belief in the life of the Hereafter is far better than an irresponsible life based on its rejection and this observation may convince them to believe in the Hereafter.
