Majma al-Zawaid — Hadith 15915

Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrated: When the day of Sayyidah Umm Habibah (may Allah be pleased with her) with the Prophet (peace and blessings be upon him) came, someone knocked at the door. The Prophet (peace and blessings be upon him) said: "Look and see who it is." They said: "It is Mu'awiyah." The Prophet (peace and blessings be upon him) said: "Give him permission to come in." He came in, and there was a pen on his ear with which he used to write. The Prophet (peace and blessings be upon him) said: "O Mu'awiyah! Why is there a pen on your ear?" He said: "It is a pen that I have kept ready for Allah and His Messenger (peace and blessings be upon him)." The Prophet (peace and blessings be upon him) said: "May Allah Almighty reward you with good on behalf of your Prophet. By Allah! I did not appoint you as a scribe except by revelation from Allah, and whatever I do, small or great, is in accordance with the revelation of Allah. How will you be when Allah Almighty clothes you in a shirt?" The narrator said: Meaning, grants him the caliphate. Then Sayyidah Umm Habibah (may Allah be pleased with her) stood up and came and sat before the Prophet (peace and blessings be upon him), and said: "O Messenger of Allah! Will Allah Almighty clothe my brother in a shirt?" The Prophet (peace and blessings be upon him) said: "Yes! But there will be some shortcomings in it." Sayyidah Umm Habibah (may Allah be pleased with her) said: "O Messenger of Allah! Pray to Allah Almighty for him." The Prophet (peace and blessings be upon him) said: "O Allah! Grant him guidance, keep him away from evils, and forgive him in the Hereafter and in this world."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains al-Sari bin Asim, who is da'if (weak).
