It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When you seek something you need and wish to succeed, then say: 'La ilaha illallahu wahdahu la sharika lahu, al-Aliyyu al-Azim; la ilaha illallahu wahdahu la sharika lahu, al-Halimu al-Karim; bismillahi alladhi la ilaha illa huwa al-Hayyu al-Halim; subhanallahi Rabbi al-arshi al-azim, wal-hamdu lillahi Rabbi al-alamin' (There is no god but Allah, He is alone and has no partner, the Most High, the Most Great. There is no god but Allah, He is alone and has no partner, the Most Forbearing, the Most Generous. In the name of Allah, besides whom there is no god, the Ever-Living, the Most Forbearing. Glory be to Allah, the Lord of the Mighty Throne, and all praise is for Allah, the Lord of the worlds.) 'As though, on the Day they see what they are promised, they had not remained (in the world) except for an hour of a day. (This is) a notification; so will any be destroyed except the defiantly disobedient people?' 'As though, on the Day they see it, they had not remained (in the world) except for an evening or its morning.' 'Allahumma inni as'aluka mujibati rahmatik, wa aza'ima maghfiratik, wal-ghanimata min kulli birr, was-salamata min kulli dhanb; Allahumma la tada' li dhanban illa ghafartah, wa la hamman illa farrajtah, wa la daynan illa qadaytah, wa la hajatan min hawa'iji al-dunya wal-akhirati illa qadaytaha bi-rahmatika ya Arhama al-rahimin' (O Allah, I ask You for the deeds that make Your mercy due, the means that make Your forgiveness certain, a share of every righteous deed, and safety from every sin. O Allah, leave me no sin but that You forgive it, no grief but that You remove it, no debt but that You settle it, and no need among the needs of this world and the Hereafter but that You fulfil it by Your mercy, O Most Merciful of those who show mercy!)"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Anas (may Allah be pleased with him) only with this chain; Yahya bin Sulayman is alone in narrating it."
