Al-Mughirah bin Shu'bah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ used to say at the conclusion of prayer: "La ilaha illallahu wahdahu la sharika lahu, lahul-mulku, wa lahul-hamdu, wa Huwa 'ala kulli shai'in Qadir. Allahumma la mani'a lima a'tayta, wa la mu'tiya lima mana'ta, wa la yanfa'u dhal-jaddi, minkal-jaddu (there is no true god except Allah. He is One and He has no partner with Him, His is the sovereignty and His is the praise, and He is Omnipotent. O Allah! None can deny that which You bestow and none can bestow that which You hold back; and the greatness of the great will be of no avail to them against You)."

[Al-Bukhari and Muslim].

وعن المغيرة بن شعبة رضي الله عنه أن رسول الله ﷺ، كان إذا فرغ من الصلاة وسلم قال : "لا إله إلا الله وحده لا شريك له، له الملك وله الحمد، وهو على كل شيء قدير. اللهم لا مانع لما أعطيت، ولا معطي لما منعت، ولا ينفع ذا الجد منك الجد" ((متفق عليه)).
