Al-Israa 17:79

And wake up during the night and pray, as an additional prayer for you [O Prophet], so your Lord may raise you to a praised status[70].

[70] Al-Maqām al-Mahmūd (the position of the Grand Intercession) is granted to the Prophet Muhammad (ﷺ).

And from [part of] the night, pray[769] with it [i.e., recitation of the Qur’ān] as additional [worship] for you; it is expected that[770] your Lord will resurrect you to a praised station.[771]

[769] Literally, "arise from sleep for prayer."
[770] This is a promise from Allāh (subḥānahu wa taʿālā) to Prophet Muḥammad (ﷺ).
[771] The position of intercession by permission of Allāh and the highest degree in Paradise.

79. And in some parts of the night (also) offer the Salât (prayer) with it (i.e. recite the Qur’ân in the prayer), as an additional prayer (Tahajjud optional prayer - Nawâfil) for you (O Muhammad صلى الله عليه و سلم). It may be that your Lord will raise you to Maqâm Mahmûd (a station of praise and glory, i.e. the honour of intercession on the Day of Resurrection.)[14].

[14] (V.17:79)
A). Narrated Ibn ‘Umar رضي الله عنهما "On the Day of Resurrection the people will fall on their knees and every nation will follow their Prophet and they will say, ‘O so-and-so! Intercede (for us with Allâh)’, till (the right of) of intercession will be given to the Prophet (Muhammad صلى الله عليه وسلم) and that will be the day when Allâh will raise him to Maqâm Mahmûd (a station of praise and glory i.e the honour of intercession on the Day of Resurrection)". (Sahih Al-Bukhari, Vol.6, Hadith No.242)
B). Narrated Jâbir bin ‘Abdullâhرضي الله عنهما: Allâh’s Messenger صلى الله عليه وسلم said, "Whoever, after listening to the Adhân (call for the prayer) says, ‘O Allâh, the Lord of this complete call and of this prayer, which is going to be established! Give Muhammad Al-Wasîlah and Al-Fadîlah* and raise him to Maqâm Mahmûd , which You have promised him,’ will be granted my intercession for him on the Day of Resurrection." (Sahih Al-Bukhari, Vol.6, Hadith No.243).
* Al-Wasîlah is the highest position in Paradise which is granted to the Prophet صلى الله عليه وسلم particularly; Al-Fadîlah is the extra degree of honour which is bestowed on him above all creation.

And some part of the night awake for it, a largess for thee. It may be that thy Lord will raise thee to a praised estate.
