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 Jabir bin `Abdullah:
Allah's Messenger (ﷺ) said, "Whoever, after listening to the Adhan (for the prayer) says, 'O Allah, the Lord of this complete call and of this prayer, which is going to be established! Give Muhammad Al-Wasila and Al-Fadila and raise him to Al-Maqam-al-Mahmud which You have promised him,' will be granted my intercession for him on the Day of Resurrection."
