Allah's Will and Permission

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

And how many angels there are in the heavens whose intercession will not avail at all except [only] after Allāh has permitted [it] to whom He wills and approves.
