(Fuswilath) 41 : 9
قُلْ أَئِنَّكُمْ لَتَكْفُرُونَ بِالَّذِي خَلَقَ الْأَرْضَ فِي يَوْمَيْنِ وَتَجْعَلُونَ لَهُ أَنْدَادًا ۚ ذَٰلِكَ رَبُّ الْعَالَمِينَ
You ask: Are you denying the One who has created the earth within two days, and are you ascribing substitutes to Him? That is the Lord of the worlds.
See explanation 2: 165; 39: 7-8; 40: 65.
