Show kindness towards those who have been loyal to you or have helped you out in times past . Be grateful for their help even if it was long ago .

This hadith is about how Prophet Muhammad (PBUH) showed preference to certain people in Medina known as the Ansar. The Ansar were a group of people who helped Prophet Muhammad when he first arrived in Medina and they were very loyal to him and his teachings. He showed them special favor by giving them preferential treatment over other people living in Medina at that time. He specifically mentioned five groups from among them -Banu Najjar, then of Banu 'Abu al-Ashhal and then of Banu Harith and then of Banu Khazraj and then of the clan of Banu Sa'idah - as being especially worthy settlements among all others in Medina. This hadith teaches us that we should show kindness towards those who have been loyal to us or have helped us out in times past; it also teaches us that we should be grateful for their help even if it was long ago because Allah will reward those who are grateful for His blessings no matter how small they may seem at first glance.
