Sayyiduna Ibn bin Ka'b, may Allah be pleased with him, says: Regarding Allah Almighty's statement ﴿سِيمَاهُمْ فِي وُجُوهِهِمْ مِنْ أَثَرِ السُّجُودِ﴾ "Their mark is on their faces from the trace of prostration," the Messenger of Allah, peace and blessings be upon him, said: "What is meant by this is light and radiance on the Day of Resurrection."
