Sayyiduna Umar bin Khattab (may Allah be pleased with him) sent Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) to Basra and Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) to Kufa. When Abu Musa conquered Tustar, he wrote to Umar (may Allah be pleased with him) that Tustar should be made subordinate to Basra. Sa'd also wrote that it should be made subordinate to Kufa. The messenger of Abu Musa (Mujazza'ah bin Thawr or Shaqiq bin Thawr) arrived first and met Umar (may Allah be pleased with him). When the messenger saw Umar (may Allah be pleased with him), he said takbeer, and Umar (may Allah be pleased with him) also said takbeer. The messenger said: "O Commander of the Faithful! Should Tustar be included in Basra?" Umar (may Allah be pleased with him) said: "Yes, it is the territory of Basra." Then the messenger gave the letter and informed that a person had become apostate, and we killed him. Umar (may Allah be pleased with him) said: "If only you had imprisoned him for three days and given him a loaf of bread each day, perhaps he would have repented. O Allah! I neither saw, nor ordered, nor was pleased when this news reached me."
