Fatimah (R.A.) was youngest in age of all her sisters but highest in grades. She was dearest to her father of all his daughters. He once said, “Fatimah is like soul and heart to me.” once, he said, “Fatimah will be the leader of the women in Paradise.” he further said, “What troubles Fatimah troubles me as well.”
It was the sixth year of Prophethood and Rasulullah (Sallallahu Alaihi Wasallam) had launched his preaching mission but his own clan were impeding in his way. The people of the Quraysh were trying every trick to trouble him. One day while he was performing Salãh in the Haram, on the instigation of the pagans of Makkak, Aqabah ibn Moeet brought the entrails of a camel and placed it on his neck whilst he was prostrating. Someone told Fatimah (R.A.) who was then just six years old. She came running and removed the stuff and cursed the non-believers. She, at such an early age beheld the tribulations and torments Rasulullah (Sallallahu Alaihi Wasallam) was being subject to.
Rasulullah (Sallallahu Alaihi Wasallam) awarded her the title of ‘lady of Paradise’.
It has been reported that Rasulullah (Sallallahu Alaihi Wasallam) once said, “On the Day of Resurrection a voice will be heard saying ‘ lower you heads, Fatimah bint Muhammad is being escorted along,’ then Fatimah will cross the pathway to Paradise in a flash leading seventy thousand Hoors (heavenly women).”
Rasulullah (Sallallahu Alaihi Wasallam) confided only to Fatimah (R.A.) during his last days that he would die of his illness. She wept to hear that but Rasulullah (Sallallahu Alaihi Wasallam) whispered to her that she would follow him which brought delight on her face and she smiled.
Rasulullah’s (Sallallahu Alaihi Wasallam) beloved wives pressed her much to disclose that secret, but she didn’t. She revealed it, however after his demise.
