Allah سبحانه وتعالى says in the Holy Quran:
وَقَالَ الَّذِينَ كَفَرُوا لَوْلا نُزِّلَ عَلَيْهِ الْقُرْآنُ جُمْلَةً وَاحِدَةً كَذَلِكَ
لِنُثَبِّتَ بِهِ فُؤَادَكَ
“And those who disbelieve say,’Why isn’t the Quran revealed to him in one go?’ In this way We strengthen your heart…..”
[al Furqan 25/32]
The Quran was revealed piecemeal to Rasulullah صلى الله عليه وسلم over a period of 23 years rather than all at once. Angel Jibraeel عليه السلام would come to Rasulullah صلى الله عليه وسلم with revelation at intervals and Rasulullah صلى الله عليه وسلم would be waiting eagerly. He would become perturbed and worried if Jibraeel عليه السلام did not arrive. When he would finally arrive with revelation, it would strengthen the heart of Rasulullah صلى الله عليه وسلم.
Human beings are naturally forgetful and it takes constant bombardment and repetition for a message to find a place in one’s heart. Many of us fail to act upon the teachings of deen because they have not been etched in our minds and engraved in our hearts. For this reason it is vital that a person regularly and consistently attends gatherings of ilm (knowledge) because one is constantly reminded ; one’s heart is strengthened and this is the method of the Quran and sunnah of Rasulullah صلى الله عليه وسلم as demonstrated in the above verse. When a person continues to attend such gatherings over many years, there will come a time when he will see the benefit of all that learning, for example, in a situation such as a calamity or misfortune.
