It is narrated from Hazrat Abu Huraira (may Allah be pleased with him): I once asked the Holy Prophet (peace and blessings be upon him), "Who will be the most fortunate to receive your intercession on the Day of Resurrection?" The Holy Prophet (peace and blessings be upon him) replied, "I had thought that you would be the first among my Ummah to ask me about this, because I see your eagerness for knowledge. The one who sincerely testifies that there is no god but Allah."
