It is narrated from Hazrat Abu Umamah (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) was smiling. We asked, "O Messenger of Allah! What makes you smile?" The Noble Prophet (peace and blessings be upon him) replied, "I am amazed at that nation which is dragged towards Paradise in chains." (Their deeds are taking them towards Hell, but Allah's mercy is taking them towards Paradise.)
