وَإِذْ اتَيْنَا مُوسَى الْكِتَابَAnd (remember) when We gave Musa the Scripture, means, the Tawrah. وَالْفُرْقَانَ .. And the criterion,that is that which differentiates between truth and falsehood, guidance and deviation.. لَعَلَّكُمْ تَهْتَدُونَSo that you may be guided aright.after escaping the sea, as another Ayah in Surah Al-A`raf clearly stated,وَلَقَدْ ءَاتَيْنَا مُوسَى الْكِتَـبَ مِن بَعْدِ مَأ أَهْلَكْنَا الْقُرُونَ الاٍّولَى بَصَأيِرَ لِلنَّاسِ وَهُدًى وَرَحْمَةً لَّعَلَّهُمْ يَتَذَكَّرُونَAnd indeed We gave Musa ـ after We had destroyed the generations of old ـ the Scripture (the Tawrah) as an enlightenment for mankind, and a guidance and a mercy, that they might remember (or receive admonition). (28:43)
