Is it necessary to change one's place or speak after a supererogatory or obligatory prayer if one intends to perform another prayer thereafter, and is this specific to Friday prayer or does it include every obligatory prayer? And is there any specific manner for rising after completing the prayer and dhikr that has been reported from the Prophet, peace and blessings be upon him, or the Companions, such as rising from the right or left side?

If the obligatory prayer has been performed and one wishes to perform a supererogatory prayer afterwards, it is better to perform it at home. If one wishes to perform it in the mosque, it is better to move to another spot to differentiate between the form of the obligatory prayer and the supererogatory prayer, and to increase the number of prostration spots. Similarly, it is recommended to perform supererogatory prayers in various locations for the aforementioned wisdom. Upon concluding the prayer, there is no harm in standing up in any posture or leaving to the right or left, as no specific posture regarding this has been reported from the Prophet, peace and blessings be upon him, nor from his companions.
