Ibn Rajab رحمه الله said, “Fasting it is like a training for fasting Ramadan, so that he does not enter the fasting of Ramadan upon discomfort and inconvenience, rather he had trained himself for fasting and he had made it a habit and he had found, through fasting Shaban, the sweetness of fasting and its delight, so he enters the fasting of Ramadan with energy and vigour. Since Shaban is like a prelude to Ramadan, what was legislated in Ramadan was legislated in it; from fasting and recitation of the Quran, so that one can attain preparedness for welcoming Ramadan and for the souls to be accustomed to that, in obedience to Ar Rahman.” [Lata'if al-Maarif 138]
