It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When any one of you performs prayer in the mosque, then returns to his home, he should perform two rak'ahs in his house. A servant should continue to offer voluntary prayers in his house, because Allah Almighty sends goodness and blessings upon his house due to his prayer.
