“One who sees his own shortcomings abstains from looking into other's shortcomings. Whoever feels happy with the livelihood with which Allah provides him does not grieve over what he misses. Whoever draws out the sword of rebellion gets killed by it. Whoever strives without means perishes. Whoever enters the depths gets drowned. Whoever visits places of ill-repute receives blame.”
