The Lady Fatima

Her birthdate is commonly taken as 7 BH or 8BH or taken as 5 years after Bi'tha (which would confirm 7BH since the Prophet stayed in Mecca for 13 years). See:

*- Kulaynī, al-Kāfī, vol. 1, p. 458*

*- Ibn Shahrāshūb, Manāqib Āl Abī Ṭālib, vol. 3, p. 132*

*- Ṭabrisī, Iʿlām al-warā, vol. 1, p. 290.*

*- Balādhurī, Ansāb al-ashrāf, vol. 1, p. 403*

*- Ibn Saʿd, al-Ṭabaqāt al-kubrā, vol. 1, p. 133; vol. 8, p. 19*


Mufid believes she was born as early as 11BH (Mufīd, Masār al-sharīʿa, p. 54) and I believe there is also some others who believe 8BH but not sure can't find source right now


The date for their marriage is often taken as early 2AH or late 1AH, See:

*- Ṭūsī, al-Amālī, p. 43*

*- Ibn Ḥajar al-ʿAsqalānī, Tahdhīb al-tahdhīb, vol. 12, p. 391*

*- Maqrizī, Imtāʿ al-asmāʾ, vol. 1, p. 73.*


So her age from most-common held view to least-common would be:

9

12

15
