It was narrated from ‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him) that the Messenger of Allaah (peace and blessings of Allaah be upon him) said

“Beware of trivial sins, for they will accumulate until they destroy a man.” And the Messenger of Allaah (peace and blessings of Allaah be upon him) gave an example, likening them to people who stopped to camp in the wilderness, and they wanted to prepare some food, so one man went and brought a stick, and another man brought a stick, until they had gathered a huge pile and lit a fire, and whatever they put in the pot was cooked as a result.
