Divine signs in creation (Ayat Allah)

وَمِنْ ءَايَـٰتِهِۦٓ أَن تَقُومَ ٱلسَّمَآءُ وَٱلْأَرْضُ بِأَمْرِهِۦ ۚ ثُمَّ إِذَا دَعَاكُمْ دَعْوَةً مِّنَ ٱلْأَرْضِ إِذَآ أَنتُمْ تَخْرُجُونَ

And of His signs is that the heaven and earth stand [i.e., remain] by His command. Then when He calls you with a [single] call from the earth, immediately you will come forth.
