Almuntakhab Fi Tafsir Alquran Alkarim

And rouse up during the hours of the night to additional devotional exercise which is meritorious and adds to your credit; may Allah, your Creator, elevate you to a position of great honour, excellence and glory

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

(17:79) Besides this, offer Tahajjud Prayer *96 at night: this is an additional prayer for you. *97 That time is not far when your Lord may exalt you to a laudable position. *98

And from [part of] the night, pray with it as additional [worship] meaning

*96) The literal meaning of "Tahajjud" is to rise up by breaking sleep. Therefore, the sentence has been translated into "Offer Tahajjud Prayer", which means "Rise up from sleep after the passing of a part of night and then offer your Prayer. "
*97) "Nafl" literally means "something done in addition to an obligatory duty". This shows that the Tahajjud Prayer is in addition to the five prescribed Prayers.
*98) "....... may exalt you to a laudable position": "You may attain such a high position in this world and in the next world that people from everywhere may be full of praise for you, and you may become a praiseworthy personality." This is, as if to say, "Now your opponents are engaged in calling you names and arc trying to defame you throughout the country, and have raised a storm of false accusations against you but that time is not far when the world will ring with the echoes of your praise and in the Hereafter you will become worthy of praise by all creatures. " The exaltation of the Holy Prophet to the high position of intercession on the Day of Resurrection is also a part of that "laudable position."
