Surah Al-Jinn, ayah 27

إِلَّا مَنِ ٱرۡتَضَىٰ مِن رَّسُولٖ فَإِنَّهُۥ يَسۡلُكُ مِنۢ بَيۡنِ يَدَيۡهِ وَمِنۡ خَلۡفِهِۦ رَصَدٗا ٢٧

Illā manirtadā mir rasūlin fa innahū yasluku mim bayni yadayhi wamin khalfihī rasadā

Except whom He has approved of messengers, and indeed, He sends before him [i.e., each messenger] and behind him observers¹⁷⁷⁵
