This is the condition I observe in all that I write. It is enough for a person to go no further than what he has heard.
In describing how envy is to be treated, I have not mentioned empirical remedies or invented remembrances. Nor have I cited anything transmitted through a weak or severely weak chain, much less a worthless fabrication. Rather, I have chosen to include only what has been reliably established from the Prophet, peace and blessings be upon him, and the early generations of the Muslim community—may Allah join us with them. Since there are authentic hadiths concerning this matter, they contain, Allah willing, sufficiency for the seeker of good, a ray of light for one in need, and guidance for one seeking the right path. The matter is as Sufyān al-Thawrī, may Allah have mercy on him, is reported to have said: “If you can avoid even scratching your head except on the basis of a transmitted report, then do so.” (1)
Saīd ibn Jubayr, may Allah have mercy on him, said: “He has done well who goes no further than what he has heard.” (2) Whatever the correct position may be concerning treatment with the Quran, healing invocations, and supplications—whether the governing principle is empirical experience, which opens a very wide door, or restriction to what has been transmitted, as with other acts of worship and sunnahs—there can be no doubt that following the sunnah is far preferable to submitting to empirical practices. The Prophet Muhammad, peace and blessings be upon him, knew more about Allah than any of us, was better acquainted with Him, and was the most mindful of Him. There is no good to which he did not guide us, and the best guidance is his guidance, peace and blessings be upon him.
I nevertheless harbor some reservation about relying on experience in the sphere of treatment. We have related that the Prophet, peace and blessings be upon him, said: “If something stirs unease in your heart, leave it.” (3) Whoever is not satisfied with this position of ours should at least accept that I mention the superior treatment rather than the inferior one—and that is fairness itself—even though I do not espouse the empirical-remedy approach to treatment through healing invocations. Rather, treatment with what has been tried and whose benefit is known
