It is narrated from Ibrahim (may Allah have mercy on him) that Sayyiduna Umar bin Khattab (may Allah be pleased with him) heard a man making this supplication: "O Allah! I spend my wealth, my life (and sometimes he would say: my children) in Your path." So Sayyiduna Umar (may Allah be pleased with him) said: "Will none of you remain silent? If a trial comes, he should be patient, and if well-being is granted, he should be grateful."
