What is said when seeking a need, and the supplication for it

Sayyiduna Abdullah bin Ja'far (may Allah be pleased with him) said that Sayyiduna Ali (may Allah be pleased with him) said to me: Shall I not teach you some words which I have not even taught Sayyiduna Hasan and Sayyiduna Husayn (may Allah be pleased with them both)? When you ask for a need and would like to succeed in it, first say these words: There is no god but Allah, He is alone, He has no partner, the Most High, the Magnificent. There is no god but Allah, He is alone, He has no partner, the Most Forbearing, the Most Generous. Then ask for your need.

Khalid said that Sa'id bin al-Musayyib stated: I entered the mosque thinking that morning had come, but a long night still lay upon me, and there was no one in the mosque except me, so I stood up. Suddenly I heard the sound of someone moving behind me, and I became afraid. Then someone said: O you who have filled your heart with alarm, do not fear, or do not be afraid, and say these words: O Allah, You alone are the King, the Possessor of power; whatever matter You will comes about. Then ask for whatever occurs to you. Sa'id said: After that I never asked Allah for anything except that Allah answered my supplication.

Waki' said that Malik bin Mighwal stated: I looked for al-Hakam regarding some need but could not find him. Then I began looking for him again and found him. And al-Hakam said: Khaythamah stated: When one of you asks for his need and then his need is fulfilled, he should also ask Allah, the Lord of Honour, for Paradise. Perhaps that will be a day on which his every supplication is accepted.
