وَمِنَ الشَّيٰطِيْنِ مَنْ يَّغُوْصُوْنَ لَهٗ وَيَعْمَلُوْنَ عَمَلًا دُوْنَ ذٰلِكَۚ وَكُنَّا لَهُمْ حٰفِظِيْنَ ۙ ( الأنبياء: ٨٢ )
Wa minash Shayaateeni mai yaghoosoona lahoo wa ya'maloona 'amalan doona zaalika wa kunna lahum baafizeen (al-ʾAnbiyāʾ 21:82)
And of the devils [i.e., jinn] were those who dived for him and did work other than that. And We were of them a guardian. (Al-Anbya  : 82)
1 Mufti Taqi Usmani
And from the devils, (We subjugated for him) those who dived in water for him and did jobs other than that. And We were the One who kept watch over them.
