Riyad as-Salihin 1455 — The Book of the Remembrance of Allah

'Abdullah bin Mas'ud Narrated from:

When it was evening, the Prophet (ﷺ) used to supplicate: "Amsaina wa amsal-mulku lillah, wal-hamdu lillah. La 'ilaha illallahu wahdahu la sharika lahu (We have entered upon evening and the whole kingdom of Allah, too, has entered upon evening. Praise is due to Allah. There is none who has the right to be worshiped but Allah, the One who has no partner with Him)."He (the narrator) said: I think that he (ﷺ) used to follow the recitation with these words: "Lahul-mulku, wa lahul-hamdu, wa Huwa 'ala kulli shi'in Qadir. Rabbi as'aluka khaira ma fi hadhihil-lailati, wa khaira ma ba'daha; wa a'udhu bika min sharri ma fi hadhihil-lailati, wa sharri ma ba'daha; Rabbi a'udhu bika minal- kasali, wa su'il-kibari; Rabbi a'udhu bika min 'adhabin fin-nari, wa 'adhabin fil-qabri (His is the sovereignty and to Him is all praise due, and He is Omnipotent. My Rubb, I beg of you good that lies in this night and good that follows it, and I seek refuge in You from the evil that lies in this night and from the evil of that which follows it. My Rubb! I seek refuge in You from lethargy and the misery of old age. O Allah! I seek Your Protection from the torment of Hell-fire and the punishment of the grave)."When it was morning, he (ﷺ) would recite the same, replacing the words: "We have entered upon evening and the whole kingdom of Allah, too, has entered upon evening" with "We have entered upon morning and the whole kingdom of Allah entered upon morning." (Replace the words "Amsaina, amsa, hadhihil-lailati, ma ba'daha with Asbahna, asbaha, hadhal-yaumi, ma ba'dahu, respectively.) [Muslim].
