Allah is the One Who has made the night for you to take rest therein, and the day as insightful; indeed Allah is bountiful to mankind, but most of mankind are not thankful.
Allah has made night as darkness for sleeping and resting and day as insightful for seeking livelihood. Therefore, mankind, endowed with intelligence, should ask for bounties only from Almighty Allah and invoke only Him. But 999 in every thousand, by hiding and rejecting Adhikr—the Insight—are serving Satan and following his footsteps, as explained in verses 4: 117-118; 2: 168-169 and 36: 59-62. These Mujirims, who don’t utilize their intelligence, are ungrateful and do not have the aim of life. They will be gathered in Hell with Satan in the Hereafter. See explanation 17: 12; 32: 12; 36: 35.
