Hence, the night comer is the piercing star. The star has been named “Tariq” (night comer) because its light pierces the darkness of night. This is one of the signs of Allah (swt). Allah (swt) shows His care about humans as for example He (swt) made the sun light to brighten the day:

 {هُوَ الَّذِي جَعَلَ الشَّمْسَ ضِيَاءً وَالْقَمَرَ نُورًا}

(It is He who made the sun a shining light and the moon a derived light) (Yunus: 5)

And has created the stars to be guidance for the humans at night:

  {وَعَلَامَاتٍ ۚ وَبِالنَّجْمِ هُمْ يَهْتَدُونَ}

(And landmarks. And by the stars they are [also] guided.) (An-Nahl: 16)

As well as, the beam that comes from the star is luminous, tearing that all-out darkness, making the movement during nighttime easier.
