have sent down
and indeed, We
(are) surely Guardians.
Innaa Nahnu nazalnaz Zikra wa Innaa lahoo lahaa fizoon
Indeed, it is We who sent down the message [i.e., the Quran], and indeed, We will be its guardian.
1 Mufti Taqi Usmani
We, Ourselves, have sent down the Dhikr (the Qur’ān), and We are there to protect it.
