how to memorise the

Last week’s question was about two verses in the Qur’aan that mention the ulul-‘azm from the Messengers and the significance of the order in which the Messengers were mentioned in the two verses. Let’s read them once again:
شَرَعَ لَكُم مِّنَ الدِّينِ مَا وَصَّى بِهِ نُوحًا وَالَّذِي أَوْحَيْنَا إِلَيْكَ وَمَا وَصَّيْنَا بِهِ إِبْرَاهِيمَ وَمُوسَى وَعِيسَى أَنْ أَقِيمُوا الدِّينَ وَلَا تَتَفَرَّقُوا فِيهِ كَبُرَ عَلَى الْمُشْرِكِينَ مَا تَدْعُوهُمْ إِلَيْهِ اللَّهُ يَجْتَبِي إِلَيْهِ مَن يَشَاء وَيَهْدِي إِلَيْهِ مَن يُنِيبُ
He (Allâh) has ordained for you the same religion (Islâm) which He ordained for Nûh (Noah), and that which We have inspired in you (O Muhammad SAW), and that which We ordained for Ibrahîm (Abraham), Mûsa (Moses‎) and ‘Iesa (Jesus) saying you should establish religion (i.e. to do what it orders you to do practically), and make no divisions in it (religion) (i.e. various sects in religion). Intolerable for the Mushrikûn , is that to which you (O Muhammad SAW) call them. Allâh chooses for Himself whom He wills, and guides unto Himself who turns to Him in repentance and in obedience. (Ash-Shooraa 42:13)
وَإِذْ أَخَذْنَا مِنَ النَّبِيِّينَ مِيثَاقَهُمْ وَمِنكَ وَمِن نُّوحٍ وَإِبْرَاهِيمَ وَمُوسَى [...]

Advice Concerning The Qur’aan
Abu ‘Abdur-Rahman Ibraahim Muhammad (1) said, “Taking a few months, a year or even two years to perfect the knowledge of tajweed (the rules of reciting the Qurýan) should not be considered a waste of time. If you were to listen to the recitation of many students of knowledge and inviters to Islam, you would not notice any difference between their recitations  and the recitation of the normal, everyday person who does not recite the Qur’an properly!? This is a problem and shortcoming that the student of knowledge and the inviter to Islam should try to correct in the beginning of their quests for knowledge.”

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.”
