It is reported that Ibn ‘Umar – Allâh be pleased with him – said,
“We were the beginning [the heads] of this Ummah, and perhaps a man from the best of the Companions of Allâh’s Messenger – Allâh’s peace and blessings be upon him – and the most righteous amongst them could maintain only one chapter of the Qur`ân or thereabouts. For the Qur`ân was weighty upon them, and they were given knowledge of it or action based on it. But the last of this Ummah will find the Qur`ân light [and easy] – the child and the non-Arab will recite it, without possessing any knowledge about it.”
