“O Nafi’! The blood is boiling in me, find me a cupper, but let it be someone gentle if you can, not an old man or a young boy. For I heard the Messenger of Allah ﷺ say: ‘Cupping on an empty stomach is better, and in it there is healing and blessing, and it increases one’s intellect and memory. So have yourselves cupped for the blessing of Allah on Thursdays, and avoid cupping on Wednesdays, Fridays, Saturdays and Sundays. Have yourselves cupped on Mondays and Tuesdays, for that is the day on which Allah relieved Ayyub of Calamity, and He inflicted calamity upon him on a Wednesday, and leprosy and leucoderma only appear on Wednesdays, or on the night of Wednesday.”  

يَا نَافِعُ قَدْ تَبَيَّغَ بِيَ الدَّمُ فَالْتَمِسْ لِي حَجَّامًا وَاجْعَلْهُ رَفِيقًا إِنِ اسْتَطَعْتَ وَلاَ تَجْعَلْهُ شَيْخًا كَبِيرًا وَلاَ صَبِيًّا صَغِيرًا فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْحِجَامَةُ عَلَى الرِّيقِ أَمْثَلُ وَفِيهِ شِفَاءٌ وَبَرَكَةٌ وَتَزِيدُ فِي الْعَقْلِ وَفِي الْحِفْظِ فَاحْتَجِمُوا عَلَى بَرَكَةِ اللَّهِ يَوْمَ الْخَمِيسِ وَاجْتَنِبُوا الْحِجَامَةَ يَوْمَ الأَرْبِعَاءِ وَالْجُمُعَةِ وَالسَّبْتِ وَيَوْمَ الأَحَدِ تَحَرِّيًا وَاحْتَجِمُوا يَوْمَ الاِثْنَيْنِ وَالثُّلاَثَاءِ فَإِنَّهُ الْيَوْمُ الَّذِي عَافَى اللَّهُ فِيهِ أَيُّوبَ مِنَ الْبَلاَءِ وَضَرَبَهُ بِالْبَلاَءِ يَوْمَ الأَرْبِعَاءِ فَإِنَّهُ لاَ يَبْدُو جُذَامٌ وَلاَ بَرَصٌ إِلاَّ يَوْمَ الأَرْبِعَاءِ أَوْ لَيْلَةَ الأَرْبِعَاءِ  

“Ibn ‘Umar said: ‘O Nafi’! The blood is boiling in me. Bring me a cupper and let him be a young man, not an old man or a boy.’ Ibn ‘Umar said: ‘I heard the Messenger of Allah ﷺ say: “Cupping on an empty stomach is better, and it increases one’s intellect and memory. And it increases the memory of one who has a good memory so whoever wants to be cupped, (let him do it) on a Thursday, in the Name of Allah. Avoid cupping on Fridays, Saturdays and Sundays. Have yourselves cupped on Mondays and Tuesdays, and avoid cupping on Wednesdays, for that is the day on which the calamity befell Ayyub, and leprosy and leucoderma only appear on Wednesday or the night of Wednesday.”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْحِجَامَةُ عَلَى الرِّيقِ أَمْثَلُ وَهِيَ تَزِيدُ فِي الْعَقْلِ وَتَزِيدُ فِي الْحِفْظِ وَتَزِيدُ الْحَافِظَ حِفْظًا فَمَنْ كَانَ مُحْتَجِمًا فَيَوْمَ الْخَمِيسِ عَلَى اسْمِ اللَّهِ وَاجْتَنِبُوا الْحِجَامَةَ يَوْمَ الْجُمُعَةِ وَيَوْمَ السَّبْتِ وَيَوْمَ الأَحَدِ وَاحْتَجِمُوا يَوْمَ الاِثْنَيْنِ وَالثُّلاَثَاءِ وَاجْتَنِبُوا الْحِجَامَةَ يَوْمَ الأَرْبِعَاءِ فَإِنَّهُ الْيَوْمُ الَّذِي أُصِيبَ فِيهِ أَيُّوبُ بِالْبَلاَءِ وَمَا يَبْدُو جُذَامٌ وَلاَ بَرَصٌ إِلاَّ فِي يَوْمِ الأَرْبِعَاءِ أَوْ لَيْلَةِ الأَرْبِعَاءِ  

[Machine] I heard the Messenger of Allah ﷺ saying, "Hijama (cupping therapy) increases intelligence and improves memory. Therefore, perform hijama on the name of Allah on Thursday. Do not perform hijama on Friday, Saturday, or Sunday. And perform hijama on Monday and Tuesday. No one catches leprosy or scab except on Wednesday night." All the narrators of this hadith are trustworthy except Ghazal ibn Muhammad, who is unknown to me for his credibility or weakness. The hadith has been confirmed from Ibn Umar, without a chain of narrators or a connected chain. Ghazal ibn Muhammad is unknown.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «الْحِجَامَةُ تَزِيدُ فِي الْعَقْلِ وَتَزِيدُ فِي الْحِفْظِ فَعَلَى اسْمِ اللَّهِ يَوْمَ الْخَمِيسِ لَا تَحْتَجِمُوا يَوْمَ الْجُمُعَةِ وَلَا يَوْمَ السَّبْتِ وَلَا يَوْمَ الْأَحَدِ وَاحْتَجِمُوا يَوْمَ الِاثْنَيْنِ وَالثُّلَاثَاءِ وَمَا نَزَلَ جُذَامٌ وَلَا بَرَصٌ إِلَّا فِي لَيْلَةِ الْأَرْبِعَاءِ» رُوَاةُ هَذَا الْحَدِيثِ كُلُّهُمْ ثِقَاتٌ إِلَّا غَزَالَ بْنَ مُحَمَّدٍ فَإِنَّهُ مَجْهُولٌ لَا أَعْرِفُهُ بِعَدَالَةٍ وَلَا جَرْحٍ وَقَدْ صَحَّ الْحَدِيثُ عَنِ ابْنِ عُمَرَ مِنْ قَوْلِهِ مِنْ غَيْرِ مُسْنَدٍ وَلَا مُتَّصِلٍ غزال بن محمد مجهول

Bring me a cupper and let him be a young man, not an old man or a boy.’ Ibn ‘Umar said: ‘I heard the Messenger of Allah ﷺ say: “Cupping on an empty stomach is better, and it increases one’s intellect and memory.

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «الْحِجَامَةُ عَلَى الرِّيقِ أَمْثَلُ وَفِيهَا شِفَاءٌ وَبَرَكَةٌ وَهِيَ تَزِيدُ فِي الْعَقْلِ وَتَزِيدُ فِي الْحِفْظِ وَتَزِيدُ الْحَافِظَ حِفْظًا فَمَنْ كَانَ مُحْتَجِمًا عَلَى اسْمِ اللَّهِ فَلْيَحْتَجِمْ يَوْمَ الْخَمِيسِ وَاجْتَنِبُوا الْحِجَامَةَ يَوْمَ الْجُمُعَةِ وَيَوْمَ السَّبْتِ وَيَوْمَ الْأَحَدِ وَاحْتَجِمُوا يَوْمَ الِاثْنَيْنِ وَيَوْمَ الثُّلَاثَاءِ فَإِنَّهُ الْيَوْمُ الَّذِي صَرَفَ اللَّهُ عَنْ أَيُّوبَ فِيهِ الْبَلَاءَ وَاجْتَنِبُوا الْحِجَامَةَ يَوْمَ الْأَرْبِعَاءِ فَإِنَّهُ الَّذِي ابْتَلَى اللَّهُ أَيُّوبَ فِيهِ بِالْبَلَاءِ وَمَا يَبْدُو جُذَامٌ وَلَا بَرَصٌ إِلَّا فِي يَوْمِ الْأَرْبِعَاءِ أَوْ فِي لَيْلَةِ الْأَرْبِعَاءِ»  

"الْحُجامةُ عَلَى الرِّيق أَمْثَلُ، وَفِيها شفاءٌ وَبَرَكَةٌ، وَتَزيدُ في الْحِفْظ وفي الْعَقْل، فاحْتَجَمُوا عَلَى بَرَكَةِ الله يَوْمَ الْخَميس واجتَنبوُا الحجَامَةَ يوْم الْجُمُعَة وَالسَّبْت والأَحَدِ، واحْتَجمُوا يومَ الاثْنَين والثُّلَاثَاءِ، فَإنَّهُ الْيَوم الذِى عَافَى اللهُ فيه أَيُّوبَ منَ الْبَلاءِ، واجْتَنبُوا الحجَامَةَ يَوْم الأرْبَعَاءِ، (فإنَّهُ الْيَوم الَّذي ابْتُلى فيه أَيوبَ وَمَا يبدو جُذَامُ، ولا بَرْصُ إِلَّا في يَوْمِ الأَرْبَعاءِ أو في لَيلَةِ الأَربعاءِ" .
