“Pray to Allah to heal me.” He said: “If you wish to store your reward for the Hereafter, that is better, or if you wish, I will supplicate for you.” He said: “Supplicate.” So he told him to perform ablution and do it well, and to pray two Rak’ah, and to say this supplication: “Allahumma inni as’aluka wa atawajjahu ilaika bimuhammadin nabiyyir-rahmah. Ya Muhammadu inni qad tawajjahtu bika ila rabbi fi hajati hadhihi lituqda. Allahumma fashaffi’hu fiya (O Allah, I ask of You and I turn my face towards You by virtue of the intercession of Muhammad the Prophet of mercy. O Muhammad, I have turned to my Lord by virtue of your intercession concerning this need of mine so that it may be met. O Allah, accept his intercession concerning me)”.
Sunan Ibn Majah Book 5, Hadith 583
← Previous Hadith “The Messenger of Allah (ﷺ) came out to us and said: ‘Whoever has some need from Allah or from any of His creation, let him perform ablution and pray two Rak’ah, then let him say: La ilaha illallahul-Halimul- Karim. Subhan-Allahi Rabbil-‘arshil-‘azim. Al-hamdu Lillahi Rabbil-‘Alamin. Allahumma inni as’aluka mujibat rahmatika, wa ‘aza’ima maghfiratika, wal-ghanimata min kulli birrin, was-salamata min kulli ithmnin. As’aluka alla tada’a li dhanban illa ghafartahu, wa la hamman illa farrajtahu, wa la hajah hiya laka ridan illa qadaitaha li (None has the right to be worshipped but Allah, the Forbearing, the Most Generous. Glory is to Allah, the Lord of the Mighty Throne. Praise is to Allah, the Lord of the worlds. O Allah, I ask You for the means of Your mercy and forgiveness, the benefit of every good deed and safety from all sins. I ask You not to leave any sin of mine but You forgive it, or any distress but You relieve it, or any need that is pleasing to You but You meet it). Then he should ask Allah for whatever he wants in this world and in the Hereafter, for it is decreed.”

Sunan Ibn Majah Book 5, Hadith 582 Next Hadith → “The Messenger of Allah (ﷺ) said to ‘Abbas: ‘O uncle, shall I not give you a gift, shall I not benefit you, shall I not uphold my ties of kinship with you?’ He said: ‘Of course, O Messenger of Allah.’ He said: ‘Pray four Rak’ah, and recite in each Rak’ah the Opening of the Book (Al-Fatihah) and a Surah. When you have finished reciting, say: Subhan-Allah wal-hamdu Lillah wa la ilaha illallah wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshipped but Allah and Allah is the Most Great) fifteen times before you bow in Ruku’. Then bow and say it ten times; then raise your head and say it ten times; then prostrate and say it ten times; then raise your head and say it ten times; then prostrate and say it ten times; then raise your head and say it ten times before you stand up. That wil be seventy-five times in each Rak’ah and three hundred times in the four Rak’ah, and even if your sins are like the grains of sand, Allah will forgive you for them.’ He said: ‘O Messenger of Allah, what if someone cannot say it in one day?’ He said: ‘Then say it once in a week; if you cannot, then say it once in a month’ until he said: ‘Once in a year.’”
