قُلِ ٱدْعُوا۟ ٱلَّذِينَ زَعَمْتُم مِّن دُونِ ٱللَّهِ ۖ لَا يَمْلِكُونَ مِثْقَالَ ذَرَّةٍۢ فِى ٱلسَّمَٰوَٰتِ وَلَا فِى ٱلْأَرْضِ وَمَا لَهُمْ فِيهِمَا مِن شِرْكٍۢ وَمَا لَهُۥ مِنْهُم مِّن ظَهِيرٍۢ
Say (O Muhammad): Call upon those whom ye set up beside Allah! They possess not an atom's weight either in the heavens or in the earth, nor have they any share in either, nor hath He an auxiliary among them.
Surah Saba(34:22)
