Sayyiduna Ibn Abbas and Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "The wife of a missing husband should wait for four years." Ibn Umar (may Allah be pleased with them both) said: "For four years, she should receive maintenance from the husband's wealth." Ibn Abbas (may Allah be pleased with them both) said: "She should take a loan, and later pay it back from the husband's wealth or inheritance."
