Entertainment with singing

وَٱسْتَفْزِزْ مَنِ ٱسْتَطَعْتَ مِنْهُم بِصَوْتِكَ وَأَجْلِبْ عَلَيْهِم بِخَيْلِكَ وَرَجِلِكَ وَشَارِكْهُمْ فِى ٱلْأَمْوَٰلِ وَٱلْأَوْلَٰدِ وَعِدْهُمْ ۚ وَمَا يَعِدُهُمُ ٱلشَّيْطَٰنُ إِلَّا غُرُورًا

"Lead to destruction those whom thou canst among them, with thy (seductive) voice; make assaults on them with thy cavalry and thy infantry; mutually share with them wealth and children; and make promises to them." But Satan promises them nothing but deceit.
