Abdul Razzaq al-Badr said,
It is more rewarding to pray supererogatory prayers at home than in the masjid even if the masjid is one of the three wherein the reward is doubled. Praying at home brings life to it and whenever a home is devoid of prayer then it is devoid of life. From the benefits of praying supererogatory prayers at home is that it encourages the children to pray, expels devils from the home and brings tranquillity and peace therein.
297. ‘Abdullāh ibn Sa’d related: “I asked the Messenger of Allāh (peace be upon him) which is more meritorious, praying at home or praying at the masjid?” He replied, “You can see that my house is very close to the masjid yet besides the five obligatory prayers, I prefer to pray in my house rather than in the masjid.” [340]
Muhammad al-Amīn al-Shanqītī said,
The scholars differed on whether it is better to pray the supererogatory prayers at home or at the masjid of the Prophet (peace be upon him) because each group understood the overall texts differently. The views of the scholars are as follows:
Imam Abū Hanifah said that praying supererogatory prayers at home is better and there would be no difference in reward if they were prayed at the masjid of the Prophet (peace be upon him).
Imam al-Shafi’ī had two views reported from him as noted in Sharh Sahīh Muslim of al-Nawawī and al-Majmū’ of the same author.
Mālikī scholars hold the view that praying supererogatory prayers at the masjid of the Prophet (peace be upon him) is better than praying them at home.
It should be noted that the reward for women praying at home is greater than them praying at the masjid, be it supererogatory prayers or obligatory prayers.
Al-Nabhānī said,
The reason he (peace be upon him) preferred to offer supererogatory prayers at home was so the blessings of prayer encompass the home and the household members, through this angels enter the house and devils leave it.
