The Merit of Providing something to the Person Observing Saum (Fasting) for breaking the Fast
Arabic hadith text
وعن أم عمارة الأنصارية، رضي الله عنها أن النبي صلى الله عليه وسلم دخل عليها فقدمت إليه طعامًا فقال " كلي" فقالت: إني صائمة، فقال رسول الله صلى الله عليه وسلم: "إن الصائم تصلي عليه الملائكة إذا أكل عنده حتى يفرغوا" وربما قال: "حتى يشبعوا" ((رواه الترمذي وقال: حديث حسن)).
Translation
Umm 'Umarah Al-Ansariyah (May Allah be pleased with her) reported
Once the Prophet (ﷺ) visited us and I served him some food. He (ﷺ) asked me to eat. I replied that I was observing (optional) fast. He (ﷺ) said, "When people eat by a person observing fast, the angels keep asking Allah's forgiveness for that person until they have had their fill."[At-Tirmidhi].
