Riyad as-Salihin, Book 17, Hadith 1488 (In-Book) ⓘ
Abul-Fadl Al-`Abbas bin `Abdul-Muttalib (ra) reported: I asked the Messenger of Allah to teach me a supplication. He said, "Beg Allah for safety (from all evils in this world and in the Hereafter)." I waited for some days and then I went to him again and asked him: "O Messenger of Allah Teach me to supplicate something from Allah." He said to me, "O Al-`Abbas, the uncle of Messenger of Allah! Beseech Allah to give you safety (Al-`afiyah ) in this life and in the Hereafter."[At- Tirmidhi].
وعن أبي الفضل العباس بن عبد المطلب رضي الله عنه قال: قلت يا رسول الله: علمني شيئًا أسأله الله تعالى، قال: "سلوا الله العافية" فمكثت أيامًا، ثم جئت فقلت: يا رسول الله: علمني شيئًا أسأله الله تعالى، قال لي: "يا عباس يا عم رسول الله سلوا الله العافية في الدنيا والآخرة". ((رواه الترمذي وقال: حديث حسن صحيح)).
