Sura Luqmān 31:29

أَلَمْ تَرَ أَنَّ ٱللَّـهَ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّ يَجْرِىٓ إِلَىٰٓ أَجَلٍ مُّسَمًّى وَأَنَّ ٱللَّـهَ بِمَا تَعْمَلُونَ خَبِيرٌ

a-lam tara annā allāha yūliju l-layla fī l-nahāri wa-yūliju l-nahāra fī l-layli wa-sakhkhara l-shamsa wa-l-qamara kullun yajrī ila ajalin musamman wa-anna allāha bi-mā taʿmalūna khabīrun

Seest thou not that Allah merges Night into Day and he merges Day into Night; that He has subjected the sun, and the moon (to his Law), each running its course for a term appointed; and that Allah is well-acquainted with all that ye do?

Sura Luqmān 31:31

أَلَمْ تَرَ أَنَّ ٱلْفُلْكَ تَجْرِى فِى ٱلْبَحْرِ بِنِعْمَتِ ٱللَّـهِ لِيُرِيَكُم مِّنْ ءَايَٰتِهِۦٓ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍ لِّكُلِّ صَبَّارٍ شَكُورٍ

a-lam tara annā l-fulka tajrī fī l-baḥri bi-niʿmati allāhi li-yuriyakum min āyātihi inna fī dhālika la-āyātin li-kulli ṣabbārin shakūrin

Seest thou not that the ships sail through the ocean by the Grace of Allah?- that He may show you of His Signs? Verily in this are Signs for all who constantly persevere and give thanks.
