Sahih al-Bukhari 4718
Sahih al-Bukhari · Book 65: Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh)) · The Statement of Allah the Exalted: "It may be that your Lord will raise you to Maqām Mahmūd (a station of praise and glory, i.e., the honour of intercession on the Day of Resurrection) ." (V.17:79)
Narrated Ibn `Umar:
حَدَّثَنِي إِسْمَاعِيلُ بْنُ أَبَانَ ، حَدَّثَنَا أَبُو الأَحْوَصِ ، عَنْ آدَمَ بْنِ عَلِيٍّ ، قَالَ سَمِعْتُ ابْنَ عُمَرَ ، رضى الله عنهما يَقُولُ إِنَّ النَّاسَ يَصِيرُونَ يَوْمَ الْقِيَامَةِ جُثًا، كُلُّ أُمَّةٍ تَتْبَعُ نَبِيَّهَا، يَقُولُونَ يَا فُلاَنُ اشْفَعْ، حَتَّى تَنْتَهِيَ الشَّفَاعَةُ إِلَى النَّبِيِّ صلى الله عليه وسلم فَذَلِكَ يَوْمَ يَبْعَثُهُ اللَّهُ الْمَقَامَ الْمَحْمُودَ.
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).
