Sayyidah Maymunah (may Allah be pleased with her) narrates: the Prophet (peace and blessings be upon him) stood in the row of the men and the women and said: O company of women! When you hear the adhan and iqamah of this Abyssinian, say the words that he says, and for every letter you will receive a million degrees. Sayyiduna Umar (may Allah be pleased with him) said: This is for the women; what is there for the men? The Prophet (peace and blessings be upon him) said: Double that, O Umar. Then the Prophet (peace and blessings be upon him) turned towards the women and said: Any woman who obeys, fulfils her husband's right, remembers his goodness, and does not betray him regarding herself or his wealth, there will be a difference of only one degree between her and the martyrs in Paradise. If her husband is a believer and of good character, she will be his wife in Paradise too; otherwise Allah Almighty will marry her to one of the martyrs.
Al-Tabarani recorded it with two chains. In one of them it is mentioned that Abdullah al-Jazari narrated it from Sayyidah Maymunah (may Allah be pleased with her). One chain contains a narrator named Mansur bin Sa'd, and I do not know him. Its chain also contains Abbad bin Kathir, in whom there is great weakness; a group declared him da'if (weak). The rest of its narrators are thiqat (trustworthy). And in the other chain there is a group of narrators whom I do not know.
