It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "Jibril (peace be upon him) came to the Prophet (peace and blessings be upon him) and said: 'Surely Allah Almighty commands you to supplicate with these words, for He will certainly grant you one of them: Allahumma inni as'aluka ta'jila 'afiyatika, wa sabran 'ala baliyyatika, wa khurujan min al-dunya ila rahmatik (O Allah, I ask You for the speedy coming of Your well-being, for patience upon Your trial, and for departing from this world to Your mercy).'"
