Surah 6. Al-An'am
Ayah 154 - 155
154ثُمَّ ءَاتَيْنَا مُوسَى ٱلْكِتَـٰبَ تَمَامًا عَلَى ٱلَّذِىٓ أَحْسَنَ وَتَفْصِيلًا لِّكُلِّ شَىْءٍ وَهُدًى وَرَحْمَةً لَّعَلَّهُم بِلِقَآءِ رَبِّهِمْ يُؤْمِنُونَ
155وَهَـٰذَا كِتَـٰبٌ أَنزَلْنَـٰهُ مُبَارَكٌ فَٱتَّبِعُوهُ وَٱتَّقُوا۟ لَعَلَّكُمْ تُرْحَمُونَ
[154-155] Then,We had given to Moses the Book to complete the blessing for those who adopted the righteous attitude; it contained details about all important things, and was a perfect guidance and mercy. (And it had been given to the children of Israel so that) the people might believe in the (ultimate) meeting with their Lord.136 And likewise have We sent down this Book, which is a perfect blessing; so follow this and adopt the God fearing attitude so that mercy may be shown to you.
136"..... 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.
