Anas bin Malik (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said to me, "Dear son, when you enter your house, say As-Salamu 'Alaikum to your family, for it will be a blessing both to you and to your family."
Commentary
Many people, on returning home, feel belittled in saying As-Salamu 'Alaikum to their household. In fact, As-Salam is a prayer for goodness, blessing and peace, and one should have no complex about it.
