An-Nahl - 16:2

يُنَزِّلُ الْمَلآئِكَةَ بِالْرُّوحِ مِنْ أَمْرِهِ عَلَى مَن يَشَاء مِنْ عِبَادِهِ أَنْ أَنذِرُواْ أَنَّهُ لاَ إِلَـهَ إِلاَّ أَنَاْ فَاتَّقُونِ
[16:2]
He sends down the angels with the inspiration by His commandment on whom He pleases of His servants, saying: Give the warning that there is no god but Me, therefore be careful (of your duty) to Me.
He doth send down His angels with inspiration of His Command, to such of His servants as He pleaseth, (saying): "Warn (Man) that there is no god but I: so do your duty unto Me."
He sendeth down the angels with the Spirit of His command unto whom He will of His bondmen, (saying): Warn mankind that there is no Allah save Me, so keep your duty unto Me.
