It is better that all of the supererogatory (prayers) are in the home, except for what has been legislated (to be performed) in the masjid, such as the night prayer during Ramadhan. So for example the sunnah before Dhuhr is better to be done at home, and the sunnah after Dhuhr (likewise) is better in the home. And the sunnah before Fajr is (better) done in the home, and the sunnah after Maghrib is (better) done in the home and the sunnah after Eesha is better to be done in the home.
All of the Nawaafil (supererogatory) are better (to be performed) in the home, due to the statement of the Prophet – sallallaahu alaihi wa sallam – : “The best prayer of a man is (the one performed) in his house, except the obligatory prayers”And the wisdom (behind) the naafila prayer being better in the house is: that the home does not become like a grave, i.e. He does not pray in it. And all of the prayers are a blessing.
Secondly that he makes his family accustomed with the prayer, due to this you will find the young child if he sees his father praying he goes and prays next to him, he stands with him, he bows with him, he prostrates with him and he sits with him. Even if he (the child) doesn’t say a thing, however he follows (his father in the prayer) and this is a booty, that you make your family accustomed to (performance) of the prayer.
