Uphold loyalty & faithfulness at all times .

In this hadith, the Prophet Muhammad is emphasizing the importance of loyalty and faithfulness. He mentions four tribes - Aslam, Ghifar, Muzainah, and Tamim - to illustrate his point. He says that these four tribes are better than another four tribes - Asad, Ghatafan, Banu 'Amir bin Sa'sa'ah - because they have been more loyal and faithful to their commitments. This hadith teaches us that loyalty and faithfulness are important values in Islam; they should be upheld at all times in order to maintain good relationships with others. Furthermore, it also teaches us that treachery should be avoided as it can lead to negative consequences for both parties involved in a relationship or agreement.
