How do we know when a sentence is finished in Arabic?
For instance, looking below:

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُحِلُّوا شَعَائِرَ اللَّهِ وَلَا الشَّهْرَ الْحَرَامَ وَلَا الْهَدْيَ وَلَا الْقَلَائِدَ وَلَا آمِّينَ الْبَيْتَ الْحَرَامَ يَبْتَغُونَ فَضْلًا مِنْ رَبِّهِمْ وَرِضْوَانًا ۚ وَإِذَا حَلَلْتُمْ فَاصْطَادُوا ۚ وَلَا يَجْرِمَنَّكُمْ شَنَآنُ قَوْمٍ أَنْ صَدُّوكُمْ عَنِ الْمَسْجِدِ الْحَرَامِ أَنْ تَعْتَدُوا ۘ وَتَعَاوَنُوا عَلَى الْبِرِّ وَالتَّقْوَىٰ ۖ وَلَا تَعَاوَنُوا عَلَى الْإِثْمِ وَالْعُدْوَانِ ۚ وَاتَّقُوا اللَّهَ ۖ إِنَّ اللَّهَ شَدِيدُ الْعِقَابِ

Is there any punctuation or no?
