Al-Hāfidh Ibn Rajab (D.795H), rahimahullah, stated,
Whoever is shown mercy in Ramadan has truly been shown mercy. And whoever is deprived of the good of Ramadan is truly deprived. And whoever doesn’t take a provision for his hereafter in Ramadan is blameworthy. And whoever doesn’t gain benefit during this month, then when is he going to gain benefit? And whoever doesn’t get closer to his Lord during Ramadan will only continue to be distant (from Allah).
