The Prophet ﷺ said: If anyone has himself cupped on the 17th, 19th and 21st it will be a remedy for every disease. (Using translation from Abū Dāʾūd 3861)   

قَالَ رَسُولُ اللهِ ﷺ مَنِ احْتَجَمَ لِسَبْعَ عَشْرَةَ وَتِسْعَ عَشْرَةَ وَإِحْدَى وَعِشْرِينَ كَانَ شِفَاءً مِنْ كُلِّ دَاءٍ  

[Machine] "The Messenger of Allah, ﷺ , said: The best of what you hope in (or seek protection in) is the seventeenth, nineteenth, and twenty-first, as narrated by Al-Zuhri from the Prophet, ﷺ , directly."  

رَسُولَ اللهِ ﷺ قَالَ خَيْرُ مَا تَحْتَجِمُونَ فِيهِ سَبْعَ عَشْرَةَ وَتِسْعَ عَشْرَةَ وَإِحْدَى وَعِشْرِينَ وَرَوَاهُ أَيْضًا الزُّهْرِيُّ عَنِ النَّبِيِّ ﷺ مُرْسَلًا  

[Machine] "From the Prophet ﷺ , he said: 'Whoever gets hijama (cupping therapy) done on Tuesday, in the seventeenth of the month, it will be a cure for the ailments of the entire year.' Abu Sa'ad al-Malini informed us, Abu Ahmad bin 'Adi al-Hafiz narrated to us, Abu Khalifah narrated to us, Abu al-Rabi' al-Zahrani narrated to us, Salam al-Tawil mentioned it."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنِ احْتَجَمَ يَوْمَ الثُّلَاثَاءِ لِسَبْعَ عَشْرَةَ مِنَ الشَّهْرِ كَانَ دَوَاءً لَدَاءِ السَّنَةِ أَخْبَرَنَاهُ أَبُو سَعْدٍ الْمَالِينِيُّ أَنْبَأَ أَبُو أَحْمَدَ بْنُ عَدِيٍّ الْحَافِظُ ثنا أَبُو خَلِيفَةَ ثنا أَبُو الرَّبِيعِ الزَّهْرَانِيُّ ثنا سَلَّامٌ الطَّوِيلُ فَذَكَرَهُ  

[Machine] Whoever performs Hijama on Tuesday of the seventeenth night of the month, Allah will remove a year's worth of illness from him.  

مَنِ احْتَجَمَ يَوْمَ الثُّلَاثَاءِ لِسَبْعَ عَشْرَةَ خَلَتْ مِنَ الشَّهْرِ أَخْرَجَ اللهُ مِنْهُ دَاءَ سَنَةٍ  

[Machine] Narrated Abu Hurayrah, may Allah be pleased with him, in a raised chain of narration that is abandoned and not worthy of mentioning: Ali ibn Ahmad ibn Abdan informed us that Ahmad ibn Ubayd Al-Saffar reported to us. He said: Hisham ibn Ali Al-Sirafi reported to us that Abu Salamah narrated to him. He said: Abu Ali Al-Rawdbary reported to us that Muhammad ibn Bakr reported to us that Abu Dawud reported to us that Musa ibn Ismail, who is Abu Salamah, reported to me that Abu Bakrah Bakkar ibn Abdul Aziz reported to me that my aunt, Kabshah bint Abu Bakrah, informed me that her father used to prohibit his family from practicing cupping on Tuesdays. He claimed that the Prophet ﷺ said that Tuesday is the day of bloodletting, and during it there is a specific hour in which the wording of Abu Dawud's hadith is not accepted. The narration of Ibn Abdan has a similar meaning to the suspended prohibition, but its chain is not strong. And Allah knows best.  

عَنْ أَبِي هُرَيْرَةَ ؓ مَرْفُوعًا وَهُوَ مَتْرُوكٌ لَا يَنْبَغِي ذِكْرُهُ أَخْبَرَنَاهُ عَلِيُّ بْنُ أَحْمَدَ بْنِ عَبْدَانَ أنبأ أَحْمَدُ بْنُ عُبَيْدٍ الصَّفَّارُ ثنا تَمْتَامٌ ثنا أَبُو سَلَمَةَ قَالَ وَحَدَّثَنَا هِشَامُ بْنُ عَلِيٍّ السِّيرَافِيُّ ثنا أَبُو سَلَمَةَ الْمِنْقَرِيُّ ح وَأَخْبَرَنَا أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنبأ مُحَمَّدُ بْنُ بَكْرٍ ثنا أَبُو دَاوُدَ ثنا مُوسَى بْنُ إِسْمَاعِيلَ وَهُوَ أَبُو سَلَمَةَ أَخْبَرَنِي أَبُو بَكْرَةَ بَكَّارُ بْنُ عَبْدِ الْعَزِيزِ أَخْبَرَتْنِي عَمَّتِي وَهِيَ كَبْشَةُ بِنْتُ أَبِي بَكْرَةَ أَنَّ أَبَاهَا كَانَ يَنْهَى أَهْلَهُ عَنِ الْحِجَامَةِ يَوْمَ الثُّلَاثَاءِ وَيَزْعُمُ عَنْ رَسُولِ اللهِ ﷺ أَنَّ يَوْمَ الثُّلَاثَاءِ يَوْمُ الدَّمِ وَفِيهِ سَاعَةٌ لَا يَرْقَأُ لَفْظُ حَدِيثِ أَبِي دَاوُدَ وَرِوَايَةُ ابْنِ عَبْدَانَ بِمَعْنَاهُ النَّهْيُ الَّذِي فِيهِ مَوْقُوفٌ غَيْرُ مَرْفُوعٍ وَإِسْنَادُهُ لَيْسَ بِالْقَوِيِّ وَاللهُ أَعْلَمُ  

[Machine] "That the Messenger of Allah, ﷺ , said: 'Whoever performs hijama (cupping therapy) on Wednesday and Saturday, and sees blood, then let him not blame anyone but himself.' Sulayman bin Arqam is weak, narrated from Ibn Sam'an, Sulayman bin Yazid, and Al-Zuhri, also weak, narrated from Al-Hasan bin Salit, from Ibn Musayyib, from Abu Hurairah, elevated, and he is also weak. The report from Al-Zuhri, from the Prophet, ﷺ , is disconnected. And Allah knows best."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنِ احْتَجَمَ يَوْمَ الْأَرْبِعَاءِ وَيَوْمَ السَّبْتِ فَرَأَى وَضَحًا فَلَا يَلُومَنَّ إِلَّا نَفْسَهُ سُلَيْمَانُ بْنُ أَرْقَمَ ضَعِيفٌ وَرُوِيَ عَنِ ابْنِ سَمْعَانَ وَسُلَيْمَانَ بْنِ يَزِيدَ عَنِ الزُّهْرِيِّ كَذَلِكَ أَيْضًا مَوْصُولًا وَهُوَ أَيْضًا ضَعِيفٌ وَرُوِيَ عَنِ الْحَسَنِ بْنِ الصَّلْتِ عَنِ ابْنِ الْمُسَيِّبِ عَنْ أَبِي هُرَيْرَةَ ؓ مَرْفُوعًا وَهُوَ أَيْضًا ضَعِيفٌ وَالْمَحْفُوظُ عَنِ الزُّهْرِيِّ عَنِ النَّبِيِّ ﷺ مُنْقَطِعًا وَاللهُ أَعْلَمُ  

[Machine] The Messenger of Allah ﷺ said, "Verily, in Friday there is an hour when no Muslim asks Allah for anything, except that Allah will grant him his request. This hour is not known except by some people who are suffering from a disease that cannot be cured, and the intercession of Attaf bin Khalid is weak. Yahya bin Al-Ala'a, who is unreliable, narrated the hadith with a chain from Al-Husayn bin Ali, in which he was raised, and it is not attributed to anything."  

قَالَ رَسُولُ اللهِ ﷺ إِنَّ فِي الْجُمُعَةِ سَاعَةً لَا يَحْتَجِمُ فِيهَا مُحْتَجِمٌ إِلَّا عَرَضَ لَهُ دَاءٌ لَا يُشْفَى مِنْهُ عَطَّافُ بْنُ خَالِدٍ ضَعِيفٌ وَرَوَى يَحْيَى بْنُ الْعَلَاءِ الرَّازِيُّ وَهُوَ مَتْرُوكٌ بِإِسْنَادٍ لَهُ عَنِ الْحُسَيْنِ بْنِ عَلِيٍّ فِيهِ حَدِيثًا مَرْفُوعًا وَلَيْسَ بِشَيْءٍ
