Asking Allah by the Prophet is deemed permissible by the consensus of the top scholars (mujtahids). Tawassul is seeking to gain benefit or to alleviate harm by mentioning a Prophet or a righteous Muslim, in honor of the mentioned, with the firm belief that Allah is the Creator of benefit and harm. In Suratul-Ma`idah, Ayah 35 means, “Seek the means of obedience to Allah.” In the hadith related and authenticated by At-Tabaraniyy, The Prophet taught the blind man to ask Allah by him. The blind man did so, and Allah returned his sight to him.
