Prostration of Gratitude Every Friday for the Extension of Life

The questioner:
Honorable Shaykh, may Allah grant you success. A person says: I prostrate in prostration of gratitude every Friday because Allah has extended my life by so many weeks. Is this permissible?

The Shaykh:
He extended his life by how much?

The questioner:
By a week. Every Friday he prostrates in prostration of gratitude.

The Shaykh:
He extended his life by a week? I tell you that he did not extend his life by a week. This is your life that was decreed for you. Yes. Also, this is a religious innovation (bid'ah) to prostrate every Friday. Except for the prostration in the Friday prayer, the Fajr prayer, and when the imam prostrates upon reciting the prostration surah, the people prostrate with him; that is a recommended practice (sunnah). But for you to prostrate because Allah lengthened your life and because you did not die before the coming Friday, that is a religious innovation (bid'ah). Yes.
