Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:

The Messenger of Allah (ﷺ) said, "Every slave of Allah who observes Saum (fasting) for one day for the sake of Allah, Allah will draw his face farther from Hell-fire to the extent of a distance to be covered in seventy years." <b>[Al-Bukhari and Muslim]</b>.

وعن أبي سعيد الخدري، رضي الله عنه قال‏:‏ قال رسول الله صلى الله عليه وسلم ‏

‏ ما من عبد يصوم يومًا في سبيل الله إلا باعد الله بذلك اليوم وجهه عن النار سبعين خريفًا‏

‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏

<b>Guidance from the Hadith:</b><br> 1) One of the greatest acts in terms of reward is to observe fast along with Jihad in the cause of Allah, for this combines the two virtues.<br> 2) It shows the merit of sincerity towards Allah Almighty in observing voluntary fast, as a person will not fast during days of Jihad except because he is completely sincere to his Lord.
