“Indeed, winter is the spring of the believer because during it he enjoys himself in the gardens of obedience to (Allaah) and wanders in the fields of worship, and his heart strolls along in devotion to the acts of worship facilitated within it, just like the animals revel in the pastures of spring; so they put on weight and (the state of) their bodies improve.
Likewise, during winter the believer’s religion is improved through what Allaah has made easy of acts of obedience; for indeed the believer is able to fast the days of winter without difficulty or being troubled by hunger and thirst because its days of fasting are short and cold, and the difficulty in fasting is unnoticed. And it has been reported in Tirmidhee from the Prophet SallAllaahu 3alayhi wa sallam who said:
“Fasting in winter is an (easily acquired) booty.” (1)Imaam Ibn Rajab (rahimahullaah) stated in Lataa-if Al-Ma3aarif 326
