Are the aforementioned supplications permissible in Islamic law?

The supplication "O Lord of the Seven Oft-Recited Verses and the Magnificent Qur'an" is impermissible, because the Qur'an is the speech of Allah and one of His attributes, not a created thing. Ibn Abbas (may Allah be pleased with both of them) objected to whoever said "Lord of the Qur'an." A Muslim must beware of the supplications of innovators and adhere to the supplications transmitted from the Prophet (peace and blessings of Allah be upon him), who was given comprehensive words. Following him leads to gaining Allah's love, mercy, forgiveness, and guidance, such as the supplication of Abu Bakr Al-Siddiq (may Allah be pleased with him): "O Allah, I have wronged myself greatly, and none forgives sins except You, so grant me forgiveness from You, and have mercy on me, for You are the All-Forgiving, the Most Merciful."
