Abu al-Sawwar al-Adawi relates that it is narrated from Sayyiduna Jundub bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever prays the morning prayer is under the protection of Allah," or he said something similar. And it has also reached me that the Messenger of Allah (peace and blessings be upon him) said: "Whoever violates my protection, I will be his opponent, and whomever I oppose, I will overcome."
