The Ruling on Prolonging Prostration in the Final Rak'ah

Question:
The questioner asks: Is it part of the Sunnah to lengthen the prostration in the final rak'ah, whether in the obligatory prayer or the voluntary prayer?

Answer:
No, this is contrary to the Sunnah. The prayer should be balanced, with no part being long and another short; the standing, bowing, and prostration should be balanced. It should also be gradual; one may lengthen the beginning of the prayer and lighten the end, making it gradual, as the Prophet (peace and blessings be upon him) used to do. As for the opposite, where one lightens the beginning of the prayer and lengthens the end, no, this is contrary to the Sunnah. Yes.
