Zaid bin Khalid Al-Juhani narrated that the Messenger of Allah (s.a.w) said: "Shall l not inform you of the best of witnesses? The one who comes with his testimony before being asked for it".
The Prophet Muhammad ﷺ was teaching his companions about the importance of honesty and truthfulness in providing evidence or testimony when needed. He taught them that those who come forward without being asked are more reliable than those who wait until they are asked for their help or knowledge. By doing this we can show our commitment to justice and truthfulness which is a great virtue in Islam as well as other religions around the world.
