Supplication for Anxiety and Grief

When my respected teacher was ill, in hospital, his honourable father, Shaykh Mawlana Adam (Allah preserve him) advised him to constantly supplicate with the following du'a taught to us by Allah's Messenger (Allah bless him and give him peace). My respected teacher says that it proved very effective and he felt peace at heart, despite his pains and illness.

Sayyiduna Abdullah ibn Mas'ud said:

'Allah's Messenger (Allah bless him and give him peace) said:

"Any servant [of Allah] who is afflicted with any worry or grief and he says...(the following du'a)...Allah (the Great and Almighty) will remove his worry, and replace his grief with joy."

They (the Companions) asked: "Should we learn these words?"

He replied: "Certainly. Anyone who hears them should learn them."'

The du'a is:

اَللّهُمَّ إنِّيْ عَبْدُكَ وَابْنُ عَبْدِكَ وَابْنُ أمَتِكَ نَاصِيَتِيْ بِيَدِكَ مَاضٍ فِيَّ

حُكْمُكَ عَدْلٌ فِيَّ قَضَاؤُكَ أسْألُكَ بِكُلِّ اسْمٍ هُوَ لَكَ سَمَّيْتَ بِهِ نَفْسَكَ

أوْ أنْزَلْتَهُ فِيْ كِتَابِكَ أوْ عَلَّمْتَهُ أحَدًا مِنْ خَلْقِكَ أوِ اسْتَأْثَرْتَ بِهِ فِيْ

عِلْمِ الْغَيْبِ عِنْدَكَ أنْ تَجْعَلَ الْقُرْآنَ رَبِيْعَ قَلْبِيْ وَنُوْرَ صَدْرِيْ

وَجِلَاءَ حُزْنِيْ وَذَهَابَ هَمِّيْ

Translation:

"O Allah, I am Your slave, son of Your male servant, and son of Your female servant. My forelock is in Your Control. Your command for me prevails. Your judgement concerning me is just. I beseech You through every name of Yours, by which You have called Yourself, or which You have sent down in Your Book, or which You taught to any one of Your creations, or which You preferred to keep among Your guarded secrets, to make the Great Qur'an the springtime of my heart, the light of my eyes, the remedy of my grief, and dispeller of my anxieties." (Ahmad: 4318, rigorously authenticated [Sahih])
