Silsilat al-Ahadith al-Sahihah

Sayyiduna Anas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Sitting with the people who remember Allah from the Fajr prayer until sunrise is more beloved to me than freeing four slaves from the descendants of Isma'il (peace be upon him), and likewise, sitting with those who remember Allah from the Asr prayer until sunset is more beloved to me than freeing four slaves."
