FususAlHikam

Make a daily habit of reciting the lesson you memorized for that day, or what you already have memorized, or a portion of what you have already memorized, in nafil salaah daily.

Lets say today you had a quarter juz lesson to memorize, you memorized it and recited it to your teacher and got checked off on it. Find some time in the day and re-recite it while standing in nafil salaah, you will memorize it a lot stronger than before.

Or lets say that you already are a hafiz, make a daily habit of reciting some portion of the Quran in nafil salaah. You will notice in a short time that your Quran will be even more stronger than before.

Or lets say you have some portion of the Quran memorized, make a daily habit of reciting what you have memorized in nafil salaah. You will find that your Quran will be much stronger than before.

My shaikh Hazrat Mufti sahib (db) had given this tip to students memorizing the Holy Quran. I have yet to meet a person who practiced upon this advice and didnt reap its benefits. Practice on it and see its benefits.
