It is narrated from Abdur Rahman bin Abi Amrah Ansari that Sayyiduna Uthman bin Affan (may Allah be pleased with him) came to the mosque for the Isha prayer and saw that there were few people, so he lay down at the back of the mosque waiting for people to gather so that their number would increase. Then Ibn Abi Amrah came and sat with Sayyiduna Uthman bin Affan (may Allah be pleased with him). Sayyiduna Uthman bin Affan (may Allah be pleased with him) asked him, "Who are you?" Ibn Abi Amrah told him his name, so Sayyiduna Uthman bin Affan (may Allah be pleased with him) asked, "How much of the Qur'an have you memorized?" Ibn Abi Amrah informed him, then Sayyiduna Uthman bin Affan (may Allah be pleased with him) said to him, "Whoever is present at the Isha prayer, it is as if he has worshipped for half the night, and whoever is present at the congregation of the morning prayer, it is as if he has worshipped the whole night."
