Imam Maalik مالك بن أنس بن مالك بن أبي عامر · Chapters on Supplication

He bears witness, from Abu Hurairah and Abu Sa’eed Al-Khudri, that they bear witness, from the Messenger of Allah, that he said: “There is no group that remembers Allah, except that the angels encompass them, mercy covers them, and tranquility descends upon them: and Allah remembers (mentions) them before those who are with Him.”

“When the Prophet (ﷺ) would bid farewell to a man, he would take his hand, and not let it go until the man let go of the hand, of the Prophet, and he would say: ‘I entrust to Allah your religion, your trusts, and the last of your deeds (Astawdi`ullāha dīnaka wa amānataka wa ākhira `amalik).’”

concerning the saying of Allah: O our Lord, give us good in this world, and good in the Hereafter. He said: “Knowledge and worship in this world, and Paradise in the Hereafter.”
