Sayyiduna Anas bin Malik (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "That I sit with a people remembering Allah from Fajr until sunrise is dearer to me than everything upon which the sun rises; and that I sit with a people remembering Allah from after Asr until sunset is dearer to me than freeing eight slaves from the descendants of Isma'il whose blood money is twelve thousand."
