Silsilat al-Ahadith al-Sahihah

Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: “Avoid minor sins. (And do not consider them insignificant, reflect that) some people camp in a valley, one person brings a stick, and another brings one... (one by one, so many sticks are gathered that) they light a fire and bake bread with it. In the same way, if one is taken to account for minor sins, they too can destroy.”

It is narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him), he says that the Messenger of Allah (peace and blessings of Allah be upon him) said: “Beware of those sins which are considered insignificant. The example of those sins which are regarded as trivial is like a group of people who camped in a valley; one man brought a stick, another brought another stick, until (so many sticks were gathered that) they baked their bread with them. And indeed, when the reckoning of minor sins is taken from the one who committed them, they will destroy him.”

Sayyidah Aisha (may Allah be pleased with her) says that the Messenger of Allah (peace and blessings of Allah be upon him) said to me: "O Aisha! Avoid sins that are considered insignificant, for indeed, there will also be questioning from Allah regarding them."
