And We have made the night and day two signs, and We (17:12)

Almuntakhab Fi Tafsir Alquran Alkarim

We made the night and the day two outward and visible signs of an inward and spiritual grace. We effaced the light from the entity of the night and put it out in obscure darkness to hide things from view. We made the day a visible entity for objects to be perceptible by the sense of sight in order to betake yourselves to Providence, for His bounty, and in order to know the number of the years. Also to reckon the time occupied by the sun in its apparent passage through the signs of the Zodiac and the period of the earths revolution round the sun forming a natural unit of time and you be able to compute time and determine it by calculation. And everything did We expound and make plain and abounding in detail

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(17:12) Behold! We have created day and night as two signs: We have deprived the sign of night of light and made the sign of day bright to enable you to seek bounty of your Lord and to reckon months and years. Thus We have made everything manifestly distinct. *13

*13) Allah invites man to study the wisdom that underlies variety in the world and not get confused and long for monotonous uniformity. In fact, the whole system is based on variety, distinctiveness and diversity in things. For the sake of illustration Iet us take the case of the signs of day and night: "You see these underlying opposite things daily in your life. If you just consider the underlying wisdom, you will find that without this variety there would have been hardly any activity in the world. Likewise great wisdom lies in the creation of the people with different temperaments, thoughts and inclinations. If Allah had made aII men righteous by birth or annihilated disbelievers and wicked people and left onlv believers and submissive people in the world, the purpose of men's creation could not leave been realized. Therefore, . it is wrong to desire that there should only be day and no night. The righteous thing is that these people, who have got the light of guidance, should exert their utmost to remove the darkness of deviation. It is their duty that if they find darkness like that of night, they should pursue it like the sun so that the light of guidance should re-appear".

دیکھو، ہم نے رات اور دن کو دو نشانیاں بنایا ہے رات کی نشانی کو ہم نے بے نور بنایا، اور دن کی نشانی کو روشن کر دیا تاکہ تم اپنے رب کا فضل تلاش کر سکو اور ماہ و سال کا حساب معلوم کر سکو اِسی طرح ہم نے ہر چیز کو الگ الگ ممیز کر کے رکھا ہے
