Sayyiduna Abu Umamah (may Allah be pleased with him) said: We were with the Messenger of Allah (peace and blessings be upon him), and he made a long supplication which we could not memorise. Then he said: "I will tell you of something that gathers all of this. Say: O Allah, we ask You for what Your Prophet Muhammad, Your servant and Your Messenger, asked You for, and we seek Your refuge from what Your Prophet Muhammad, Your servant and Your Messenger, sought Your refuge from. You are the One whose help is sought, and upon You rests the conveying, and there is no power and no strength except through Allah."
