The Messenger of Allah ﷺ said, "For me to sit with a group of people remembering Allah the Exalted from the dawn prayer until the sun rises is more beloved to me than freeing four descendants of Ismail. And for me to sit with a group of people remembering Allah from the afternoon prayer until the sun sets is more beloved to me than freeing four."
قال رسول الله ﷺ: لأن أقعد مع قوم يذكرون الله تعالى من صلاة الغداة حتى تطلع الشمس أحب إلي من أن أعتق أربعة من ولد إسماعيل، ولأن أقعد مع قوم يذكرون الله من صلاة العصر إلى أن تغرب الشمس أحب إلي من أن أعتق أربعة.
Abu Dawud (3667) narrated it from Muhammad bin Muthanna, [who said] Abdul-Salam, meaning Ibn Muthahhar (Abu Zafar), narrated to me, [who said] Musa bin Khalaf Ammi narrated to us, from Qatada, from Anas, and he mentioned it.Its isnad is hasan because of Abdul-Salam bin Muthahhar and Musa bin Khalaf, for both of them make the hadith hasan.
