وَسَخَّرَ لَكُم مَّا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ جَمِيعًا مِّنْهُ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَتَفَكَّرُونَ Qur’an Al-Jathiya (45:13)Wasakhkhara lakum ma fee alssamawati wama fee alardi jameeAAan minhu inna fee thalika laayatin liqawmin yatafakkaroona
I.e., by endowing man, alone among all living beings, with a creative mind and, thus, with the ability to make conscious use of the nature that surrounds him and is within him.
Cf. xxxi. 20, and n. 3605. The sea was only one example of Allah's cherishing care in making all things in nature available for the use of man, through the genius and faculties which He has given to man. Man should never forget that it is all "as from Him", i.e., from Allah.
