Is it permissible, in Islamic law, to write verses from the Holy Quran, such as Surah Al-Baqarah, Al Imran, An-Nisa, Al-Ma'idah, and Al-An'am, using various methods like writing with saffron, or hanging them up, or placing them in water and drinking it, for purposes of healing, or protection, or facilitating matters, or pregnancy, as mentioned in the examples, and do these actions have a sound merit in Islamic Sharia?

Designating specific verses and chapters from the Qur'an with particular virtues or for fulfilling needs without evidence is considered an innovation (bid'ah). However, it is permissible for a Muslim to recite a chapter or verse to fulfill a need based on the general prophetic tradition: "Whoever recites the Qur'an, let him ask Allah by it." As for claiming and propagating the designation of something specific for a specific need without evidence, this is among the newly invented matters, especially if it involves hanging the Qur'an (as an amulet), which is an issue debated among scholars, and many verified scholars have deemed it forbidden.
