Can a husband lead his wife in the supererogatory (Sunnah Ratibah) prayers, such as those associated with Fajr, Dhuhr, Asr, Maghrib, Isha, Shafa, and Witr? Is performing the supererogatory (Sunnah Ratibah) prayers at home better than in the mosque? Is it disliked to perform them in the mosque? Is the preference based on reward?

The general principle regarding supererogatory sunnah prayers is that they should be prayed individually, and it is not prescribed to habitually pray them in congregation. As for voluntary nafl prayers in congregation, they are of two types: those for which a regular congregation is prescribed, such as the Eclipse Prayer, the Prayer for Rain (Salat al-Istisqa), and Qiyam Ramadan; and those for which a regular congregation is not prescribed, such as Qiyam al-Layl (Night Prayer), the regular sunnah prayers, Salat al-Duha (Forenoon Prayer), and Tahiyat al-Masjid (Greeting of the Mosque). If this second type is occasionally performed in congregation, it is permissible. However, habitually performing them in congregation is a reprehensible innovation (bid'ah makruhah).

As for performing nafl prayers at home, it is more meritorious than performing them in the mosque, except for those for which a congregation is prescribed, such as the Eclipse Prayer and Tarawih. The proof for this is the saying of the Prophet, peace and blessings be upon him: "O people, pray in your homes, for the best prayer is a man's prayer in his home, except for the obligatory prayers." The wisdom behind this is that prayer at home is more private, more conducive to sincerity, and further removed from ostentation (riya').
