Hadith 506400
Chapter 18: Fasting - كتاب الصيام
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ حَرْمَلَةَ الأَسْلَمِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَزَالُ النَّاسُ بِخَيْرٍ مَا عَجَّلُوا الْفِطْرَ " .
Yahya related to me from Malik from Abd ar-Rahman ibn Harmala al- Aslami from Said ibn al-Musayyab that the Messenger of Allah, may Allah bless him and grant him peace, said, "People will remain in good as long as they are quick to break the fast."
