memorized the Qur’an

 They are Words that no falsehood may come to them from before them or behind them. This is even more auspicious in a time when the chests of the young men and women have become filled with that which is silly and forbidden.

 

• 17- Jannah for the one who memorized the Qur’an. Hadrat Ali (RA) reports that the Prophet (Sallallahu Alaihi Wasallam) said:
  “Anyone who knows the Quran by heart and follows the lawful and the prohibited according to it, he will be sent to Heaven by Allah U.” (Tirmidhi). As long as the memoriser of the Qur’an following the lawful and kept away from the prohibited then he will be granted Jannah.

 

•  18- Double reward for those who try hard to memorize the Qur’an. Aaishah that the Prophet (Sallallahu Alaihi wasallam) said: The likeness of the one who reads Quraan and memorizes it is that he is with the righteous honourable scribes. The likeness of the one who reads it and tries hard to memorize it even though it is difficult for him, he will have (at least) a double reward. (Al-Bukhaari, 4937)

 

So we must NEVER give up memorising the Qur’an even though we may struggle to learn a single verse for it maybe that shaythan will try hard to make a person give up knowing that he will receive double rewards for it if he continues.
