I heard the Messenger of Allah ﷺ say: If any of you is suffering from anything or his brother is suffering, he should say: Our Lord is Allah Who is in the heaven, holy is Thy name, Thy command reigns supreme in the heaven and the earth, as Thy mercy in the heaven, make Thy mercy in the earth; forgive us our sins, and our errors; Thou art the Lord of good men; send down mercy from Thy mercy, and remedy, and remedy from Thy remedy on this pain so that it is healed up.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنِ اشْتَكَى مِنْكُمْ شَيْئًا أَوِ اشْتَكَاهُ أَخٌ لَهُ فَلْيَقُلْ رَبُّنَا اللَّهُ الَّذِي فِي السَّمَاءِ تَقَدَّسَ اسْمُكَ أَمْرُكَ فِي السَّمَاءِ وَالأَرْضِ كَمَا رَحْمَتُكَ فِي السَّمَاءِ فَاجْعَلْ رَحْمَتَكَ فِي الأَرْضِ اغْفِرْ لَنَا حُوبَنَا وَخَطَايَانَا أَنْتَ رَبُّ الطَّيِّبِينَ أَنْزِلْ رَحْمَةً مِنْ رَحْمَتِكَ وَشِفَاءً مِنْ شِفَائِكَ عَلَى هَذَا الْوَجَعِ فَيَبْرَأُ  

[Machine] The Prophet ﷺ taught me a Ruqyah (healing supplication) and commanded me to use it on anyone who complained to me. He told me to say: "Our Lord, Allah, who is in the heavens, your name is sanctified, your command is in the heavens and on the earth. O Allah, just as your command is in the heavens, bestow your mercy upon us on the earth. O Allah, Lord of the good people, forgive our sins, our faults, and our offenses. Send down mercy and healing from your mercy and your healing upon anything that is bothering so-and-so until he is cured." He said: "And say this three times, then seek refuge with the two protectors (Surah Al-Falaq and Surah An-Nas) three times."  

عَلَّمَنِي النَّبِيُّ ﷺ رُقْيَةً وَأَمَرَنِي أَنْ أَرْقِيَ بِهَا مَنْ بَدَا لِي قَالَ لِي قُلْ رَبَّنَا اللهُ الَّذِي فِي السَّمَوَاتِ تَقَدَّسَ اسْمُكَ أَمْرُكَ فِي السَّمَاءِ وَالْأَرْضِ اللهُمَّ كَمَا أَمْرُكَ فِي السَّمَاءِ فَاجْعَلْ رَحْمَتَكَ عَلَيْنَا فِي الْأَرْضِ اللهُمَّ رَبَّ الطَّيِّبِينَ اغْفِرْ لَنَا حَوْبَنَا وَذُنُوبَنَا وَخَطَايَانَا وَنَزِّلْ رَحْمَةً مِنْ رَحْمَتِكَ وَشِفَاءً مِنْ شِفَائِكَ عَلَى مَا بِفُلَانٍ مِنْ شَكْوَى فَيَبْرَأُ قَالَ وَقُلْ ذَلِكَ ثَلَاثًا ثُمَّ تَعَوَّذْ بِالْمُعَوِّذَتَيْنِ ثَلَاثَ مَرَّاتٍ  

[Machine] Two men sought a cure for urinary ailments, so they went to Abu Darda. They mentioned their ailments to him, and he said, "I heard the Messenger of Allah, peace be upon him, say, 'If any one of you complains of anything, or his brother complains about something, let him say, 'Our Lord is Allah Who is in heaven, holy is Your name. Your command comes from heaven and earth, as Your mercy is in heaven, so make Your mercy in the earth. Forgive us our sins and our transgressions. Surely, You are the Lord of good people, so send down mercy from Your mercy, and healing from Your healing, and cure this illness, if it is Your will, Most High.' The two sheikhs, other than Ziyad ibn Muhammad, have confirmed the authenticity of this Hadith with all its narrators. Ziyad ibn Muhammad is a sheikh from the people of Egypt who narrates few Hadiths."  

أَنَّ رَجُلَيْنِ أَقْبَلَا يَلْتَمِسَانِ الشِّفَاءَ مِنَ الْبَوْلِ فَانْطَلَقَ بِهِمَا إِلَى أَبِي الدَّرْدَاءِ فَذَكَرَا وَجَعَ أُنْثَيَيْهِمَا لَهُ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنِ اشْتَكَى مِنْكُمْ شَيْئًا أَوِ اشْتَكَاهُ أَخٌ لَهُ فَلْيَقُلْ رَبَّنَا اللَّهُ الَّذِي فِي السَّمَاءِ تَقَدَّسَ اسْمُكَ أَمْرُكَ فِي السَّمَاءِ وَالْأَرْضِ كَمَا رَحْمَتُكَ فِي السَّمَاءِ فَاجْعَلْ رَحْمَتَكَ فِي الْأَرْضِ وَاغْفِرْ لَنَا ذُنُوبَنَا وَخَطَايَانَا إِنَّكَ رَبُّ الطَّيِّبِينَ فَأَنْزِلْ رَحْمَةً مِنْ رَحْمَتِكَ وَشِفَاءً مِنْ شِفَائِكَ عَلَى هَذَا الْوَجْهِ فَيَبْرَأُ إِنْ شَاءَ اللَّهُ تَعَالَى «قَدِ احْتَجَّ الشَّيْخَانِ بِجَمِيعِ رُوَاةِ هَذَا الْحَدِيثِ غَيْرِ زِيَادَةَ بْنِ مُحَمَّدٍ وَهُوَ شَيْخٌ مِنْ أَهْلِ مِصْرَ قَلِيلُ الْحَدِيثِ»  

"مَنِ اشْتَكَى منكم شَيئًا، أَو اشتكاه أَخٌ لَهُ ، فَليَقُلْ "ربنا الله الذي في السماءِ والأَرضِ كَمَا رَحْمَتُكَ في السماء، فَاجْعَلْ رَحْمَتَك في الأَرْضِ، اغْفِرْ لَنا حُوبَنَا وَخَطَايَانَا، أَنْتَ ربُّ الطيِّبين، أَنْزِلْ رحْمَةً من رَحْمَتِكَ، وشِفَاءً من شِفَائِكَ عَلَى هَذَا الوجَع فَيَبْرَأ".
