Jarir bin 'Abdullah (May Allah be pleased with him) reported: Messenger of Allah ﷺ said, "He who is not merciful to people Allah will not be merciful to him". Al-Bukhari and Muslim.
The Prophet Muhammad ﷺ also taught us how to practice mercy by showing us examples of his own behavior. He was known for his patience, understanding, and forgiveness even when faced with difficult situations or people who were unkind or disrespectful towards him. By following his example, we can learn how to be merciful even when it may seem difficult or impossible at times.
