It is narrated from Sayyiduna Ali (may Allah be pleased with him) that when Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) would recite the Noble Qur’an, he would keep his voice low, whereas Sayyiduna Umar Farooq (may Allah be pleased with him) would recite the Noble Qur’an in a loud voice, and Sayyiduna Ammar (may Allah be pleased with him) would sometimes recite from one surah and sometimes from another. When this was mentioned before the Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) asked Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him),“Why do you keep your voice low?”He replied,“I make the One I am supplicating to hear me.”When he asked Sayyiduna Umar (may Allah be pleased with him) about reciting in a loud voice, he replied,“I drive away Satan and wake up those who are sleeping.”The Prophet (peace and blessings be upon him) asked Sayyiduna Ammar (may Allah be pleased with him),“Why do you sometimes recite from one surah and sometimes from another?”He replied,“Have you ever heard me mixing one surah with another?”He said,“No, all are correct in their own way.”
