Assalamoualkum warrahmatullahi wabarakatahu,

is it true that the prophet had more than one or two children?

i know that prophet Muhammad (s.a.w.s) was gifted the gift of kawthar from Allah (s.w.t) that is bibi fatima (a.s) ,the queen of heavens and earth. i also heard that the prophet (pbuh) had a son that died during childbirth , other than that i never knew he had another offspring after that im not sure , please correct me if i am wrong

second inquiry: how many wives did the prophet have after bibi khatija a.s

i am aware that the prophet had multiple wives but i don’t know anyone other than bibi khadija a.s, and bibi umme salma ,after that i dont know

jazakallah
