Hadith
عن أبي أيوب رضي الله عنه أن رسول الله صلى الله عليه وسلم قال: “من صام رمضان ثم أتبعه بست من شوال كان كصيام الدهر” ((رواه مسلم)).
Abu Ayyub (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said,
“He who observes As-Saum (the fasts) in the month of Ramadan, and also observes As-Saum for six days in the month of Shawwal, it is as if he has observed As-Saum for the whole year.”
[Muslim].
