The Holy Quran, Surat Al-Jinn - الجن

Ayat
27
إِلَّا مَنِ ارْتَضَى مِن رَّسُولٍ فَإِنَّهُ يَسْلُكُ مِن بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِ رَصَداً
Save unto every messenger whom he hath chosen, and then He maketh a guard to go before him and a guard behind him
28
لِيَعْلَمَ أَن قَدْ أَبْلَغُوا رِسَالَاتِ رَبِّهِمْ وَأَحَاطَ بِمَا لَدَيْهِمْ وَأَحْصَى كُلَّ شَيْءٍ عَدَداً
That He may know that they have indeed conveyed the messages of their Lord. He surroundeth all their doings, and He keepeth count of all things.
