He said: Abul Qasim Ja'far b. Muhammad b. Qawlawayh (may ALLAH (SWT) bless him with mercy) reported to me from al-Husain b. Muhammad b. Amir, from Ahmad b. Alawiyyah, from Ibrahim b. Muhammad al-Thaqafi, who reported from Tawabah b. al- Khaleel, who reported from Uthman b. Isa who reported from Abu Abdil Rehman, who reported from JA'FAR B. MUHAMMAD (ASWS) that:
Once when the PROPHET (SAWW), peace be upon him and his progeny, was travelling, he dismounted and then performed five prostrations (Sijdah). When he mounted again, one of his companions said: "We saw you do something, O MESSENGER of ALLAH (SWT), which you never did before."
He said: "Yes, Jibraeel came to me and gave me glad news that ALI (ASWS) belongs in Paradise. So I went into prostration to thank ALLAH (SWT).
When I raised my head, he said: FATIMA (SAWS) belongs in Paradise.' I went to prostrate again to thank ALLAH (SWT).
And when I raised my head, he said: 'AL-HASAN (ASWS) AND AL-HUSAIN (ASWS)are the masters of the youths of Paradise.' So I prostrated to thank ALLAH (SWT).
And when I raised my head, he said: 'And those who love them belong in Paradise.' So I prostrated to thank ALLAH (SWT).
And when I raised my head, he said: 'And those who love the people who love them (Ahlul Bait) belong in Paradise.' (So I prostrated to thank ALLAH (SWT))."
