Imam Sadiq (as) said: A man came to al-Hasan ibn Ali and told him: O my master, would you please help me in solving my problem. He put on his shoes and went with him.
In his way, he saw al-Husayn while he was praying. He told the man: Where was the man, pointing to Husayn ibn Ali, when you needed help? The man said: O my master! I looked for him, but I was informed that he is praying.
Imam Husayn said: If he had helped you, it would be better for him that a one-month pray.”
