Ziyad bin Nu'aym narrates: I heard Abu Dharr al-Ghifari (may Allah be pleased with him) say on the pulpit: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever draws closer to Allah by a handspan, Allah draws closer to him by a forearm's length; and whoever draws closer to Him by a forearm's length, Allah draws closer to him by an arm's span; and whoever comes towards Allah, the Mighty and Majestic, walking, Allah, the Mighty and Majestic, comes towards him running. And Allah is the Most High and Most Majestic, Allah is the Most High and Most Majestic, Allah is the Most High and Most Majestic."
