<b>Guidance from the Hadiths:</b><br> 1) It is preferable to perform all supererogatory prayers at home, which is the Prophet’s guidance and his Sunnah.<br> 2) When a person offers a supererogatory prayer at home, Allah puts goodness therein by virtue of his prayer, as his family will follow his example, and there he is farther from showing off his worship. Moreover, the reward of a supererogatory prayer at home is multiplied. There are other benefits related to this. However, if this serves no purpose but following the Prophet’s Sunnah, this would be good enough.
