Chapter: It is recommended to offer voluntary prayers in one’s house although it is permissible to offer them in the masjid

Observe some of your prayers in your houses and do not make them graves.

Pray in your houses, and do not make them graves.

When any one of you observes prayer in the mosque he should reserve a part of his prayer for his house, for Allah would make the prayer as a means of betterment in his house.

The house in which remembrance of Allah is made and the house in which Allah is not remembered are like the living and the dead.

Do not make your houses as graveyards. Satan runs away from the house in which Surah Baqara is recited.

The Messenger of Allah (ﷺ) made an apartment with the help of the leaves of date trees or of mats. The Messenger of Allah (ﷺ) went out to pray in it. People followed him and came to pray with him. Then they again came one night and waited (for him), but the Messenger of Allah (ﷺ) delayed in coming out to them. And when he did not come out, they cried aloud and threw pebbles at the door. The Messenger of Allah (ﷺ) came out in anger and said to them: By what you have been constantly doing, I was inclined to think that it (prayer) might not become obligatory for you. So you must observe prayer (optional) in your houses, for the prayer observed by a man in the house is better except an obligatory prayer.

" Had this (Nafl) prayer become obligatory for you, you would not be able to observe it."
