How is healing achieved through seeking forgiveness (Istighfar), what is the required number of times to seek forgiveness per day, is it permissible to seek forgiveness with the intention of achieving a specific goal or healing from an illness? And what are the methods of healing through the Quran?

Seeking forgiveness (Istighfar) is a means of attracting blessings, repelling misfortunes, and attaining mercy and sustenance. Among its forms is to couple it with sincere repentance. It should be performed consistently (70-100) times daily, in addition to the Istighfar recited in prayer and as expiation for an assembly. The Quran is a healing for what is within it of verses. Healing with the Quran occurs by reading what is easy to recite from it, asking Allah through it, by means of legal ruqyah, by blowing into the hands and wiping with them, and by reciting Al-Mu'awwidhat (the last three surahs of the Quran) and Al-Fatihah.
