﴿ وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ مِنۢ بَعْدِ مَآ أَهْلَكْنَا ٱلْقُرُونَ ٱلْأُولَىٰ بَصَآئِرَ لِلنَّاسِ وَهُدًۭى وَرَحْمَةًۭ لَّعَلَّهُمْ يَتَذَكَّرُونَ ﴾

“And [then,] indeed, after We had destroyed those earlier generations [of sinners], We vouchsafed unto Moses [Our] revelation as a means of insight for men, and as a guidance and grace, so that they might bethink themselves [of Us].”

And verily We gave Moses the Scripture the Torah after We had destroyed the former generations the people of Noah ‘Ād Thamūd and others containing eye-openers for mankind basā’ira is a circumstantial qualifier referring to al-kitāb ‘the Scripture’ the plural of basīra which is the perceptive light of the heart in other words illumination for the hearts of mankind and as guidance from error for those who implement it and mercy for those who believe therein that perhaps they might remember that they might be admonished by the admonitions it the Scripture contains.
