Follow Islamic traditions instead of those from other religions; Take care of one’s appearance; Respect oneself by looking presentable; Dye your gray hairs/beard if you wish too .

The hadith narrated by Abu Huraira states that Allah's Messenger said that the Jews and the Christians do not dye their grey hair or beards. Therefore, Muslims should do the opposite of what they do, which is to dye their grey hair and beards. This hadith teaches us that it is permissible for Muslims to dye their grey hair or beards in order to look more presentable. It also encourages us to follow our own traditions instead of following those of other religions. Furthermore, this hadith reminds us that we should take care of our appearance as it reflects on our faith in Islam.
