quran:21:27 –

They cannot precede Him in word, and they act by His command.  

They do not ˹venture to˺ speak before Him — they only speak after He has spoken, and they act according to His command, that is, following ˹His issuing of˺ it.
القرآن:٢١:٢٧ –

لَا يَسْبِقُونَهُ بِالْقَوْلِ وَهُمْ بِأَمْرِهِ يَعْمَلُونَ  

{لا يسبقونه بالقول} لا يأتون بقولهم إلا بعد قوله {وهم بأمره يعملون} أي بعده.
