Ruling on Musaajalah with Qur’aanic verses (i.e., where a person who has memorized Qur’aan is asked to quote a verse starting with the letter with which another verse ended)
Question

                What is the ruling on the musajalah of the Qura’anic verses in order to remember the verses and to fill the time with something of value? It is not meant by it to belittle Allah’s verses.
Praise be to Allah.There is nothing wrong with 
    using means that help one to remember and properly memorize the Holy 
    Qur’aan, such as competitions and testing those who have memorized it, and 
    paying attention to verses that sound similar, rather these are things that 
    are recommended (mustahabb), because they reinforce one’s memorization and 
    help with it. 
That includes what is 
    called musaajalah, where a verse is recited to the hafiz then he is asked to 
    recite a verse that starts with the letter with which the first verse 
    ended. 
And Allaah knows best.
