Book 10: Call to Prayers (Adhaan) · Hadith 99
Hadith text
Narrated Abu Mas`ud:A man came and said, "O Allah's Messenger (ﷺ)! I keep away from the morning prayer because so-and-so (Imam) prolongs it too much." Allah's Messenger (ﷺ) became furious and I had never seen him more furious than he was on that day. The Prophet (ﷺ) said, "O people! Some of you make others dislike the prayer, so whoever becomes an Imam he should shorten the prayer, as behind him are the weak, the old and the needy
Abu Mas'ud (رضی اللہ عنہ) bataate hain ke ek shaks aaya aur kaha: "Ya Rasoolallah! Main Fajr ki jamaat se door rehta hoon kyunke falaan (Imam) usse bahut lamba kar deta hai." Allah ke Rasool gusse ho gaye, maine unhe us din se zyada gussa mein kabhi nahi dekha. Nabi ne farmaya: "Aye logon! Tum mein se kuch log doosron ko namaz se bezaar kar dete hain, isliye jo bhi Imam bane, namaz halki kare, kyunke uske peechhe kamzor, budhe aur zaroorat-mand log hote hain."
