Read the Qur’an, as it will come as an intercessor for its companions on the Day of Resurrection
Authentic hadithعن أبي أمامة رضي الله عنه قال: سمعتُ رسولَ اللهِ صلى الله عليه وسلم يقولُ: «اقْرَؤُوا القرْآنَ؛ فَإنَّهُ يَأتِي يَوْمَ القِيَامَةِ شَفِيعًا لأَصْحَابِهِ».
Abu Umāmah (may Allah be pleased with him) reported: I heard the Messenger of Allah (may Allah’s peace and blessings be upon him) say: "Read the Qur’an, as it will come as an intercessor for its companions on the Day of Resurrection."
Explanation
The Prophet (may Allah's peace and blessings be upon him) encouraged his Ummah to read the Qur’an, and said that if they do so, on the Day of Resurrection Allah, the Almighty, will make the reward of their Qur'an recitation come in the form of an independent entity who will intercede for those who had read the Qur'an, those who were preoccupied with it, and those who abided by its commands and prohibitions.
