Ziyad bin Kusaib Al-'Adawi said: "I was with Abu Bakrah under the Minbar of Ibn 'Amir while he was giving a Khutbah wearing a fine garment. Abu Bilal said: 'Look at our Amir wearing clothes of wickedness!' So Abu Bakrah said: Be quiet! I heard the Messenger of Allah(s.a.w) saying: "Whoever insults Allah's Sultan on the earth, Allah disgraces him".
We can also learn from this hadith that it is important to think before we speak or act. Abu Bilal was about to insult Abu Bakrah but he was stopped by his reminder of the Prophet Muhammad’s ﷺ words about respecting rulers. We should always take a moment before speaking or acting so that we can make sure our words and actions are pleasing to Allah and do not cause any harm or hurt anyone else’s feelings.
