<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.<br> <br> <b>Benefit:</b><br> Multiplication of the reward of a supererogatory prayer at home is proved by a Hadith narrated by Imām ‘Abdur-Razzāq al-San‘āni in which one of the Companions of the Prophet (may Allah’s peace and blessings be upon him) reported that he said:<br> “A voluntary prayer a man performs at home is better than a voluntary prayer he performs among people as much as his prayer in congregation is better than his prayer alone.”<br> This Hadith is supported by another one narrated by Imām Abu Ya‘la in which Sohaib (may Allah be pleased with him) reported that the Prophet (may Allah’s peace and blessings be upon him) said: “A voluntary prayer a man performs where people cannot see him is 25 times better than his prayer where people can see him.”<br> In Fayd al-Qadir Sharh al-Jāmi‘ al-Saghir, Al-Munāwi said:<br> “This is because supererogatory prayers are prescribed as means for drawing close to Allah on the basis of sincerity. So, the more hidden they are, the more distant a person is from show-off. Obligatory prayers, on the other hand, are prescribed for proclaiming the religion. So, it is more appropriate to show them.”
