أَلَمْ تَرَ أَنَّ ٱللَّهَ يُسَبِّحُ لَهُۥ مَن فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَٱلطَّيْرُ صَٰٓفَّٰتٍۢ ۖ كُلٌّۭ قَدْ عَلِمَ صَلَاتَهُۥ وَتَسْبِيحَهُۥ ۗ وَٱللَّهُ عَلِيمٌۢ بِمَا يَفْعَلُونَ
Hast thou not seen that Allah, He it is Whom all who are in the heavens and the earth praise, and the birds in their flight? Of each He knoweth verily the worship and the praise; and Allah is Aware of what they do.
