Book 30: Fasting · Hadith 109
Hadith text
Narrated Ibn `Abbas:The Prophet (ﷺ) came to Medina and saw the Jews fasting on the day of Ashura. He asked them about that. They replied, "This is a good day, the day on which Allah rescued Bani Israel from their enemy. So, Moses fasted this day." The Prophet (ﷺ) said, "We have more claim over Moses than you." So, the Prophet fasted on that day and ordered (the Muslims) to fast (on that day)
Ibn Abbas (رضی اللہ عنہما) bataate hain: Nabi Madina aaye aur Yahudiyon ko Ashura ke din roza rakhte dekha. Unhone unse iski wajah pucchi. Unhone jawab diya: "Yeh ek achha din hai, wahi din jis din Allah ne Bani Israel ko unke dushman se bachaya. Isliye Musa ne is din roza rakha." Nabi ne kaha: "Humara Musa par tumse zyada haqq hai." Isliye Nabi ne us din roza rakha aur (Musalmanon ko) roza rakhne ka hukum diya.
