In verse 55, it was said: وَاتَّبِعُوا أَحْسَنَ مَا أُنزِلَ إِلَيْكُم (and follow the best of what has been sent down to you). The second phrase أَحْسَنَ مَا أُنزِلَ (the best of what has been sent down) means the Qur'an, and the whole Qur'an is but ahsan, the best - and the Qur'an can be called: اَحسَںَ و اکمل (best) also in the sense that out of all scriptures - Torah, Injil, Zabur - revealed from Allah Ta’ ala, the Qur'an is the best and the most perfect. (Qurtubi)
- 39:5555
وَاتَّبِعُوا أَحْسَنَ مَا أُنْزِلَ إِلَيْكُمْ مِنْ رَبِّكُمْ مِنْ قَبْلِ أَنْ يَأْتِيَكُمُ الْعَذَابُ بَغْتَةً وَأَنْتُمْ لَا تَشْعُرُونَ
Follow the best of what has been revealed to you by your Lord before the punishment overtakes you suddenly and you are caught unawares,
