وَمِنَ ٱلَّيۡلِ فَتَهَجَّدۡ بِهِۦ نَافِلَةً۬ لَّكَ عَسَىٰٓ أَن يَبۡعَثَكَ رَبُّكَ مَقَامً۬ا مَّحۡمُودً۬ا (٧٩)
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. (79)
Hadith Bukhari: Volume 6, Book 60, Number 242:
Narrated Ibn Umar:
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 Allah), “till (the right) intercession is given to the Prophet (Muhammad) and that will be the day when Allah will raise him into a station of praise and glory (i.e. Al-Maqam -al-Mahmud).
