Is not the name of the Prophet's father, peace and blessings be upon him, Abdullah, not Ibrahim, as you mentioned in Fatwa no. 147215?

The Prophet, peace and blessings be upon him, named his son Ibrahim as a blessing, after his grandfather Ibrahim, peace be upon him. There is no contradiction between this and his direct father being Abdullah, for a grandfather is called a father in the Arabic language and in the Holy Quran, as in the saying of Yusuf: "And I have followed the religion of my fathers, Abraham, Isaac, and Jacob," and His (Allah's) saying: "As He completed it upon your fathers before, Abraham and Isaac."
