Verse 26

وَكَم مِّن مَّلَكٍ فِى ٱلسَّمَـٰوَٰتِ لَا تُغْنِى شَفَـٰعَتُهُمْ شَيْـًٔا إِلَّا مِنۢ بَعْدِ أَن يَأْذَنَ ٱللَّهُ لِمَن يَشَآءُ وَيَرْضَىٰٓ

And so many angels in the vacua, their intercession will have no benefit in the least, except after God has given permission for whomever He wills and approves.
