Ibn Qulawayh Al Qummi, Kaamil al-Ziyarat
Hanan Ibn Sadiq from his father narrates through a chain of narrators:
Abu Abdillah (Imam Sadiq [as]) asked me, 'O Sadir! Do you perform the Ziyarah of the grave of Husein [as] once every day?'
I replied, 'May I sacrifice myself for you! No.'
Imam [as] said: 'How negligent you people are! Do you perform his Ziyarah once every month?'
I replied, 'No.'
Imam [as] asked, 'What about once every year?'
I replied, 'Sometimes.'
'O Sadir! How negligent you people are toward Husein [as]. Do you not know that Allah has onemillion angels who are disheveled and covered with dust, who cry over Husein [as], and who perform his Ziyarah (at all times) and they never pause?!
O Sadir! How difficult is it for you to perform the Ziyarah of the grave of Husein [as] five times every friday and once every day?'
I replied, 'May I sacrifice myself for you. There is a great distance between us and his [as] grave.'
'Go to the roof of your house, look to the right and left, raise your head towards the sky, and then try to face the direction of the grave of Husein [as] and say:
'Assalamu Alayka Ya Aba Abdillah. Assalamu Alayka wa rahmatullahi wa barakatuh'
'Salam to you, O Aba Abdillah. Salam to you and may Allah's mercy and blessings be upon you'
By doing so, a Zawrah will be registered for you. And Zawrah is the performance of a hajj and anUmrah'
Sadir added, 'After hearing this, there were times when I would perform this Ziyarah twenty times during the day.'
'O God, carry us in the ships of Thy deliverance, give us to enjoy the pleasure of whispered prayer to Thee, make us drink at the pools of Thy love, let us taste the sweetness of Thy affection and nearness, allow us to struggle in Thee, preoccupy us with obeying Thee, and purify our intentions in devoting works to Thee, for we exist through Thee and belong to Thee, and we have no one to mediate with Thee but Thee!' Imam Sajjad ('A); Sahifa al-Sajjadiyya
