Offering the supererogatory Prayer in a spot other than that where the obligatory prayer is offered

Q 9: When people get up to offer the supererogatory Salah (Prayer), many of them change the spot where they have offered the obligatory Prayer in the Masjid (mosque). Does this have an origin in the Sunnah (whatever is reported from the Prophet)?

A: As far as we know, there is no Sahih (authentic) Hadith reported from the Prophet (peace be upon him) that indicates the desirability of changing place for offering supererogatory Salah. However, it is reported from Ibn `Umar and others of the Salaf (righteous predecessors) that they did so, and the matter is flexible.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
