Musannaf Ibn Abi Shaybah 25109 — Those who permitted blowing in ruqyah

A man of Banu Salaman bin Sa'd narrates through his mother that her maternal uncle, Sayyiduna Habib bin Fuwayk (may Allah be pleased with him), told her that his (Habib's) father took him to the Messenger of Allah (peace and blessings be upon him) when his eyes had lost their sight and he could not see anything with them. He asked him (the father) what had happened to him (Habib). The father told him, and the Messenger of Allah (peace and blessings be upon him) blew into his eyes. And I saw (Habib) threading a needle when he was eighty years old, while his eyes were white.
