5وَاختِلافِ اللَّيلِ وَالنَّهارِ وَما أَنزَلَ اللَّهُ مِنَ السَّماءِ مِن رِزقٍ فَأَحيا بِهِ الأَرضَ بَعدَ مَوتِها وَتَصريفِ الرِّياحِ آياتٌ لِقَومٍ يَعقِلونَT. B. IrvingThe alternation of night and daylight, and any sustenance God sends down from the sky with which He revives the earth after its death, and the wheeling of the winds are signs for folk who use their reason.
