Narrated by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Abu al-Qasim Ja’far ibn Muhammad, from Muhammad ibn Ya’qub, from Ali ibn Ibrahim, from Ahmad ibn Abi Abdullah, from Ziyad al-Qandi, from Abdul Rahim al-Qasir, who said: I entered upon Abu Abdullah عليه السلام and said to Imam عليه السلام: 'May I be your ransom, I have composed a supplication.' Imam عليه السلام said: 'Leave your composition aside. When a matter befalls you, turn to the Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family), and pray two rak'ahs, dedicating them to the Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family).' I said: 'How should I do that?' Imam عليه السلام said: 'Perform ghusl, pray two rak'ahs,' and Imam عليه السلام narrated the rest of the details of the supplication until the end. Then Abu Abdullah عليه السلام said: 'I guarantee, on behalf of Allah سبحانه وتعالى, that you will not leave your place until your need is fulfilled.'"
