Strive for justice when dealing with slaves & other people under your care ; Ensure they are treated fairly & given their rights as human beings regardless of their religion or race ; Never take advantage of someone's vulnerable position in society ; Strive for justice even when it comes at your own expense .

This hadith is about a man named Ash Sharid ibn Suwayd ath Thaqafi, who was instructed by his mother in her will to emancipate a believing slave. He then went to the Prophet Muhammad ﷺ for advice on how he could test if the black Nubian slave girl he owned was indeed a believer or not. The Prophet ﷺ then told him of an Islamic tradition that would help him determine whether she believed in Allah and His Messenger or not. This tradition involved testing her faith through asking her questions related to Islam, such as whether she believes in Allah and His Messenger, prays five times daily, fasts during Ramadan etc. If she answered yes to all these questions, it would be proof that she is indeed a believer and should be freed from slavery according to Islamic law. This hadith teaches us that we should always strive for justice when dealing with slaves and other people under our care; we must ensure that they are treated fairly and given their rights as human beings regardless of their religion or race. It also teaches us that we should never take advantage of someone's vulnerable position in society; instead we should always strive for justice even when it comes at our own expense.
