Believe in Allah's justice and mercy , Have faith no matter how small .

This hadith speaks to the power of faith and its ability to save a person from the Fire. Even if one has only a speck of faith in their heart, they will be saved from the punishment of Hellfire. To emphasize this point, Abu Sa'eed then recited a verse from the Quran which states that Allah does not deal unjustly with even the weight of a speck. This hadith teaches us that faith is an incredibly powerful thing and should not be underestimated or taken lightly. It also serves as an encouragement for those who may feel like their faith is too weak or insignificant; even if it is only as small as a speck, it can still save them in times of need.
