Abu Abd al-Rahman al-Sulami said: A man came to Sayyiduna Ibn Mas'ud (may Allah be pleased with him) and said: I have married a woman and I fear (her) aversion. He said: "When you go in to her, pray two rak'ahs and say: 'O Allah, bless me in my family and bless them in me. O Allah, keep us together in goodness for as long as You keep us together, and if You separate us, separate us towards goodness.'"
