وَجَعَلْنَا ٱلَّيْلَ وَٱلنَّهَارَ ءَايَتَيْنِ ۖ فَمَحَوْنَآ ءَايَةَ ٱلَّيْلِ وَجَعَلْنَآ ءَايَةَ ٱلنَّهَارِ مُبْصِرَةً لِّتَبْتَغُوا۟ فَضْلًا مِّن رَّبِّكُمْ وَلِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ ۚ وَكُلَّ شَىْءٍ فَصَّلْنَٰهُ تَفْصِيلًا
36:38; 40:62; 41:38.
10:6.
Commentary:
The verse should not be understood to mean that God first made both night and day and then the one was displaced by the other. It only means that God has made night and day such that both have their benefits for man; but whereas the benefits of the night are subtle and hidden, those of the day are clear and manifest.
Similarly, the natural phenomenon of the alternation of night and day helps man in determining the dates of the year and in preparing calendars. It has also led to the development and progress of the science of mathematics. See also 10:6.
'Day' being the symbol of happiness and prosperity and 'night' that of grief and sorrow, the verse points to two kinds of signs: (a) those that lead to a people’s prosperity and advance; and (b) those that lead to their misery and destruction. We are exhorted here to pray that we may only be shown the first kind of signs. By inference we are also exhorted to make both the time of our distress and misery and the period of our progress and prosperity means of our spiritual advancement, just as God has made both night and day as a source of great material benefits for us.
