Hadith text
Narrated Abu Sa`id:That he had heard the Prophet (ﷺ) saying, "Do not fast continuously (practice Al-Wisal), and if you intend to lengthen your fast, then carry it on only till the Suhur (before the following dawn)." The people said to him, "But you practice (Al-Wisal), O Allah's Messenger (ﷺ)!" He replied, "I am not similar to you, for during my sleep I have One Who makes me eat and drink
Abu Saeed (رضی اللہ عنہ) bataate hain: Unhone Nabi ko farmate suna: "Lagataar roza (Al-Wisal) mat rakho, aur agar tum apna roza lamba karna chaho, to sirf Sehri tak (agli subah tak) hi karo." Logon ne unse kaha: "Magar aap Al-Wisal karte hain, Ya Allah ke Rasool!" Aap ne jawab diya: "Main tum jaisa nahi hoon, kyunke apni neend mein mera koi hai jo mujhe khilata-pilata hai."
