Imam Mohammad Baqir (a.s.) or Imam Jafar Sadiq (a.s.) informed Zoraarah,
قَالَ: يَا زُرَارَةُ مَا فِي الْأَرْضِ مُؤْمِنَةٌ إِلَّا وَ قَدْ وَجَبَ عَلَيْهَا أَنْ تُسْعِدَ فَاطِمَةَ
فِي زِيَارَةِ الْحُسَيْنِ ع
‘O Zoraarah! It is necessary for every Shia on this earth to seek the pleasure and good wishes of Janabe Zahra (s.a.) through the Ziyarat of Imam Husain (a.s.).’
(Behaar al-Anwaar, vol. 101 pg. 75)
Peace be upon you O’ Aba ‘Abdillah and upon the souls which were annihilated with you. Upon you, from me, is the peace of Allah for eternity, as long as the night and the day remain and please do not make this (Ziyarat) as my last contact with you. Greetings be upon Husayn, and upon ‘Ali the son of Husayn and upon the children of Husayn and upon the companions of Husayn.
