Treat everyone with respect and kindness regardless of their differences.

This hadith is narrated by Ibn 'Abbas, who was a companion of Prophet Muhammad. It teaches us that all people are equal regardless of their size or stature. The hadith states that the little finger and the thumb are equal in size, which is a metaphor for equality among people. This means that no one should be treated differently because of their physical appearance or social status; everyone should be treated with respect and kindness regardless of their differences. This hadith also teaches us to appreciate our differences as they make us unique individuals, but at the same time we must remember to treat each other equally without prejudice or discrimination.
