HADEES - ~ Offering Supererogatory Prayers in One's House

Ahmad and Muslim relate from Jabir that the Messenger of Allah said:
"If one of you offers his prayers in the Mosque then he should make a
portion of his prayers in his house, as Allah has made his prayers in
his house a means of betterment (for him)."
Ahmad records from 'Umar that the Messenger of Allah said: "The
nawafil salah of a man in his house are a light; whoever wishes should
lighten up his house."
'Abdullah ibn 'Umar reports that the Prophet sallallahu alehi wasallam
said: "Make some of your prayers in your houses and do not turn your
houses into graves." This statement is related by Ahmad and Abu Dawud.
Abu Dawud records from Zaid ibn Thabit on sound authority that the
Messenger of Allah said: "A person's salah in his house is better than
his salah in my mosque, except for the fard salah."
These hadith prove that it is preferred to say one's nawafil prayers
in one' s house since prayers in one ' s house are better than those
that he performs in the mosque. An-Nawawi says: "The Prophet
sallallahu alehi wasallam encouraged one to offer nawafl in one's
house because then the prayers are more private and willhave less of a
chance of being done for show and will be free from defects that
vitiate good deeds. Furthermore, this will be ablessing for the house
as mercy and angels will descend on it while Satan flees from it."
