Surah Al-Qasas 28:71

Night and Day are among the Blessings of Allah and are Signs of Tawhid

Allah reminds His servants of His favors towards them by subjugating for them the night and day, without which they could not survive. He explains that if He made the night continuous, lasting until the Day of Resurrection, that would be harmful for them and would cause boredom and stress. So He says:

(which god besides Allah could bring you light) meaning, `with which you could see things and which would bring you relief'

(Will you not then hear) Then Allah tells us that if He had made the day continuous, lasting until the Day of Resurrection, that would also be harmful for them and their bodies would get tired from so much movement and activity. Allah says:

(which god besides Allah could bring you night wherein you rest) meaning, `to rest from your work and activity.'

(Will you not then see It is out of His mercy) towards you,

(that He has made for you the night and the day) He created both,

(that you may rest therein) during the night,

(and that you may seek of His bounty) during the day, by traveling, moving about and working.

(and in order that you may be grateful.) So that you may give thanks to Allah by performing all kinds of acts of worship at night and during the day. Whoever misses something during the night can make it up during the day, and vice versa. This is like the Ayah,

(And He it is Who has put the night and the day in succession, for such who desires to remember or desires to show his gratitude.) (25:62). And there are many similar Ayat.

Pada ayat ini, Allah menyuruh Rasul-Nya supaya bertanya kepada orang-orang yang mempersekutukan-Nya. Andai kata Allah menjadikan malam ini terus menerus sepanjang masa sampai hari Kiamat tanpa ada siang yang menyelinginya, apakah di antara sembahan-sembahan mereka itu kuasa dan mampu mendatangkan siang untuk dapat dimanfaatkan cahayanya? Apakah kaum musyrikin itu tidak mempergunakan pendengarannya? Mereka itu seakan-akan tuli. Kalaulah mereka mempergunakan akal sebaik-baiknya, tentu mereka akan insaf dan sadar serta mengetahui dengan yakin bahwa hanya Allah Yang Mahakuasa yang dapat mendatangkan malam untuk menggantikan siang apabila dikehendaki. Dia mendatangkan siang untuk menghapuskan malam apabila Dia kehendaki dan tiada sesuatu pun yang dapat melakukan yang demikian itu.

Firman Allah:

Dan Kami jadikan malam dan siang sebagai dua tanda (kebesaran Kami), kemudian Kami hapuskan tanda malam dan Kami jadikan tanda siang itu terang. (al-Isra'/17: 12)
