Hazrat Ibn Abi Mulaykah (may Allah have mercy on him) narrates that I saw Hazrat Abdullah bin Amr (may Allah be pleased with him) weeping. When he saw me, he said, "Are you surprised at my weeping out of fear of Allah? So if you cannot weep, then at least make a face as if you are weeping, to the extent that someone among you might say, 'Look at him, look at him.' Surely, even this moon weeps out of fear of Allah."
