Cupping increases intellect and memory

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): Nafi' said: Ibn Umar (may Allah be pleased with them both) said to me: "O Nafi', find me a cupper who is neither a young boy nor an old man, for my blood has surged (tabayyagha). And I heard the Messenger of Allah (peace and blessings be upon him) say: 'Cupping (hijamah) increases the intellect and increases memory. So (have it done) with the name of Allah on Thursday. Do not have cupping done on Friday, Saturday or Sunday; rather, have it done on Monday and Tuesday. And leprosy and vitiligo descend only on the night of Wednesday.'"
All the narrators of this hadith are trustworthy except Ghazal bin Muhammad, for he is unknown; I do not know him in terms of either reliability or criticism. However, this hadith is authentically reported from Ibn Umar (may Allah be pleased with them both) as his own statement (mawquf).

It is narrated from Nafi' that Sayyiduna Ibn Umar (may Allah be pleased with them both) said to me: "O Nafi', go and bring me a cupper, and do not bring me an old man or a young boy." And he said: "Have cupping done on Thursday with the blessing of Allah, and have cupping done on Friday as well, but do not have it done on Saturday. Have cupping done on Sunday, Monday and Tuesday, but do not have it done on Wednesday, for leprosy and vitiligo appear only on the night of Wednesday or on Wednesday."
