As for the cause of occultation...
As for how people would benefit from me during my occultation, it is like getting benefits from the sun, which is concealed by the clouds. And I am the security for the people on the face of the earth just as stars are security for the inhabitants of the heavens. Therefore do not ask what you are not in need of and do not put yourself into undue trouble. And pray more for an early reappearance as in it lies your success.
Peace be on you, O Ishaq Ibne Yaqoob and peace be on all those who follow the guidance…” 5 -Narrated to us Muhammad bin Hasan bin Ahmad bin Walid (r.a.) from Saad bin Abdullah from Ali Ibne Muhammad ar-Raazi, famous as Kulaini that he said: Narrated to me Muhammad bin Shazan bin Nuaim Nishapuri that he said: “An amount of 480 dirhams collected with me from the money that was supposed to be paid to His Eminence, Qaim (a.t.f.s.).
So I did not like sending it without rounding off the amount (to 500). Therefore I added 20 dirhams of my own and sent 500 dirhams to Muhammad bin Ja’far but I did not mention that 20 dirhams were from my side. Thus Muhammad bin Ja’far received acknowledgment from the Holy Hidden Imam (a.s.) that he sent to me in turn.
It was written on the receipt: Received 500 dirhams of which 20 were your own.” 6 - Narrated to me my father: Narrated to us Saad bin Abdullah from Ishaq bin Yaqoob that he said: I heard Shaykh Amari (r.a.) say: “I knew a man from the city with whom was an amount of money from the Imam’s share. When this amount was sent to the Imam, he returned it and stated: Take out the share of your cousins from this, which comes to 400 dirhams. The man was amazed on reading this.
When calculations were made it was indeed found that the person was having some property of his cousins in his charge. He returned some of the property and retained some. ‘ Then he gave it away as Sadaqah. It was an amount of 400 dirhams as the Imam had mentioned.
