Musnad Ahmad

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is afflicted by any calamity or grief and recites these words, Allah Almighty will remove his calamity and grief and grant him happiness in its place. These words are: «اَللّٰهُمَّ إِنِّي عَبْدُكَ وَابْنُ عَبْدِكَ وَابْنُ أَمَتِكَ نَاصِيَتِي بِيَدِكَ مَاضٍ فِيَّ حُكْمُكَ عَدْلٌ فِيَّ قَضَاؤُكَ أَسْأَلُكَ بِكُلِّ اسْمٍ هُوَ لَكَ سَمَّيْتَ بِهِ نَفْسَكَ أَوْ عَلَّمْتَهُ أَحَدًا مِنْ خَلْقِكَ أَوْ أَنْزَلْتَهُ فِي كِتَابِكَ أَوْ اسْتَأْثَرْتَ بِهِ فِي عِلْمِ الْغَيْبِ عِنْدَكَ أَنْ تَجْعَلَ الْقُرْآنَ رَبِيعَ قَلْبِي وَنُورَ صَدْرِي وَجِلَاءَ حُزْنِي وَذَهَابَ هَمِّي» 'O Allah! I am Your servant, son of Your servant, son of Your maidservant. My forelock is in Your hand. Your command over me is ever executed, and Your decree over me is just. I ask You by every name belonging to You which You have named Yourself with, or taught to any of Your creation, or revealed in Your Book, or kept with Yourself in the knowledge of the unseen, that You make the Qur'an the spring of my heart, the light of my chest, the remover of my sorrow, and the reliever of my distress.'" Someone asked: "O Messenger of Allah! Should we learn this supplication?" He said: "Why not? Whoever hears it, it is appropriate for him to learn it."
