Brief Explanation
Explanation: Winter is like spring for the believer in terms of worship, because in it the days are short and the nights are long. There is not much hardship or difficulty in fasting during the day and standing in prayer at night. Therefore, for the worshippers, it has been called a windfall. Thus, the noble statement of Sayyiduna Umar radi Allahu anhu is that winter is a windfall for the worshippers. [الزهد لأحمد : 615، صحيح]
Sayyiduna Anas radi Allahu anhu narrates that Sayyiduna Abu Hurairah radi Allahu anhu said: "Shall I not tell you about the cool windfall?" We said: "Abu Hurairah! What is that?" He replied: "Fasting in the winter season is the cool windfall." [سنن الكبري للبيهقي : 09/44،صحيح]
Ubayd bin Umair (a trustworthy Tabi‘i) says: When the winter season would come, it would be said: "O people of the Qur’an! The nights have become long for your prayers and the days have become short for your fasts. Therefore, consider it a windfall." [المصنف لا بن ابي شيبه 36138 وسنده صحيح]
