Musannaf Ibn Abi Shayba 22:41

Muhammad ibn Abd al-Rahman al-Sadusi narrated to us, from Miq'as ibn Imran, from Umm al-Darda, who said: I entered upon Aisha and said: "What is the superiority of one who recites the Quran over one who does not recite it, among those who enter Paradise?" Aisha said: "Indeed, the number of the levels of Paradise is according to the number of the verses of the Quran. So, there is no one among those who enter Paradise who is superior to one who recited the Quran."
